Hi, I'm the guy who commissioned that pic at Demoncon!
It is true (like many of the people who have commented have said) that this character, whose name is Nerina btw, did indeed start life as a Sonic-styled Vaporeon FC called Narnia made by Poisonofthedart689 who I adopted the character from and then remade as an Aestrian (an original species created by my friend charlottezxz who I was also with at Demoncon) who had become part Picollad (an original species of fish I created) which explains the fish-like features. And I also renamed her Nerina to avoid confusion with Charlotte's own water based character Nariah. (And a certain fantasy world)
Anyway, thank you very much for the pic, you did a great job!
Ha, kind of looks like an antro pokemon. I find it interesting what people ask for. I never actually wanted an image so bad that I was willing to pay somebody else to draw it for me. Now, if I could sit over your shoulder and watch you draw, we might have a deal.
