Oh how I do love aquatic scenes, perhaps that is due to being raised on the coast. Water has just always fascinated me, the textures it makes on the skin of people and rocks. Only sad fact is the wrinkled fingers, I hate that part of swimming, its impossible to hold things in my opinion.
Alma used to love to swim when he was a kid, the caverns where his people reside have just miles of submerged tunnels. Could say one of the boys hobby was to swim through thous said passages, always loved it. No, he doesn't have gills or anything, the kid is just able to just hold his breath for a long time. You kinda have to learn to when you are in an area where the nearest air bubble might not be for quite some time.
Loved playing around with effects on this image, still absolutely adore drawing crystals, one of my favorite things now I think.
