Lovely artwork! It so happens that I was just wondering what a selkie-mermaid might look like. I see you added some sort of whiskers to her head. I'm guessing that's a part of seal anatomy. The patterns on her skin were a nice touch as well. Kudos to you!
all of your artwork is absolutely beautiful! I just love the expression on her face in this one, it looks so soft and innocent. You get the expressions and colours spot-on in all of your drawings, and you draw humans and animals with an extremely high level of skill - I'm guessing you must've been to life-drawing a fair few times! (p.s I was pleasantly surprised to see you live in my neck of the woods too - I live in Newport!)
