So my little sister was hanging down on our dock a couple weeks ago and happened to spot something that we have NEVER seen in the area before: a River Otter. My parents have lived in our yard for 27 years (and we are always outside), they have never seen one before here, we didn't think they existed in our river! We suspect that this little dude may just be cruising through, since we haven't seen him (or her?) since. My sis was lucky enough to have her camera with her, and was kind enough to let me use her pics for reference.
The only part I actually referenced was the otter, and the front half only (back end was covered in greenery). I wing'd all of the foliage, the shoreline and the water. Whew. Challenging to make things look realistic sometimes when you don't have a ref.
So all painted with acrylics on a piece of watercolour paper.
