Lookin good! Nice use of a warmer color scheme. What I find interesting is the way your background is interacting with your character. The landscape is literally warping behind your character which makes him that much more important >.o b
A take on the character from the H.P. Lovecraft short story "The Shadow over Innsmouth". I see many human-fish hybrids where really quite a 'cool' or 'fearsome' aquatic animal is spliced in (shark-man, octopus head etc.) so I thought it would be fun to do something goofy like the Oranda goldfish.
That is a wonderful character. Would love to see him smoking a cigar or pipe, maybe have the smoke coming out the gills for a touch of class Maybe an antique opium pipe?
