This is very generous of you. :o
If you'd want to, you could draw my character Silvanus: https://www.weasyl.com/character/40459/silvanus & https://www.weasyl.com/submission/940240/silvanus-ref-wip
Or any of my other characters if you like them better: https://www.weasyl.com/characters/pixelhoot
I don't have a preference of medium; do whatever you feel like! The only thing I will specify is keeping it SFW.
Thanks so much for offering, and if you do decide to draw something for me I'll try my best to critique it. :>

After a bit of thought, and a lack of other people offering up suggestions, I've decided to toss a few ideas at you, mayhaps! And I'll second PixelHoot on this being very nice of you to offer.

Ample creative freedom, to run with an idea for as long or as short as you'd enjoy; a sketch or a fully colored scene, where ever your muse takes you. I present the idea of a Layleauxian Koba or two: https://www.dropbox.com/sh/smqhqbfuewmbwq5/AADVP0FzmXBG9Qb31offQ9bua?dl=0 (Warning, bit of nsfw refs in there)

Creatures of a tribal nature; primitive, swamp dwellers, and in general peaceful, if not exactly graceful thanks to their tails. Omnivores that have a highly vegetarian diet with only the rare bit of meat (Fish or insect most commonly), they don't go out of their way to hunt for food favoring instead to live off very primitive methods of farming and otherwise gathering from the land. Though they may be Warm blooded, they're not very well suited to colder climates as a good bit of their natural temperature regulation is taken directly from the current climate.

Not exactly a highly developed culture but one filled with a respect for nature, generally peaceful; communal living, low technology, a touch of mysticism and at most simple magic. Identification and the story of an individual is often presented in body paints and markings, some simple, some complex, others worn only during ritualistic events. Clothing is simple, made of leaves or leather, the occasional bit of cloth from a passing trader, though they tend to have little to offer in the way of trade goods: The occasional bit of wood work, hides and bones from the uncommon swamp dwelling predator that had threatened the tribe.

Outside of their homelands, they're prized as manual and unskilled labor and occasionally as guards or warriors because of their physical strength, endurance, and protective nature. Once you've gained one's trust, protection is readily and willingly given: After all, a trusted friend is a member of one's tribe.

When it comes to gender dimorphisim, in general the females are a touch larger then the males (A whole two inches and 30-40 lbs on average), though the males tend be a bit stronger but again, not by much. Both have the typical crest and frill along the back of their head leading down to their neck as part of their natural temperature regulation, as well as the lengthy tongue of their species. The females also have breasts, despite being an egg laying species (Both aspects divergent from their homelands thanks to some impurity and hybridization in the blood line some ages ago, when they were taken as slave stock). Culturally, there tends to not be much difference between the genders when it comes to filling a role the tribe needs.

Now, where would your mind take you when presented with such information? A lone tribal guardian, standing watch outside the huts, or even in a more modern setting as a bouncer? One swimming or traveling through the everglades of their homelands or along some forested path? Tame romance between a pair of the dinosaur like creatures? Some adventurer, far from their tribe, out seeking new experiences with members of some other race that had passed through the swamplands at some time? A tribe gathered around a shaman, telling a story of some sort, or several tending to a plot of marsh-land farming? Or even just a tame pin up of some member of the species, applying their daily paints?

I can only hope that the idea is something that would interest you; I like the species, and don't have a specific character in mind. I just like seeing where people's minds go with them. I -am- slightly biased towards females and tame, tasteful erotica, but that's personal tastes: "Nudity is fine art. Erect nudity is porn."

I'm curious to see how you would handle the texture of their hide, and the detail of body paints, as well as their natural markings. True, they tend to be generally drab browns in color and stick with whiter pigments for their body paints, that doesn't mean some color doesn't make it into the paints now and then.

When it comes to critique, what sort do you look for? How harsh do you want it to be? From what I've seen of most of your work, you've got a strong grasp of anatomy, and you do textures wonderfully with your graphite work. I don't see much in the way of backgrounds or settings, however. Is that an area you feel you need to focus on? I also -adore- your ink and copic one of Brynn; that was actually the image that most caught my eye when you had posted it up.

And again, thank you for offering these up! I can only hope I've given you and your muse something worth working on!

Howdy. So... I noticed you liked my opossum Oscar. If you would like to do something with him, I'd be honored. I have no specific requests in mind, so basically anything that would be in keeping with his character as described.

Also I got like zero formal training in art-type stuff but I'll do my best to crit wisely, should you choose to take me up on this. :)
