His mouth looks rather large, but maybe that's because sharks have large jowls? Otherwise, he looks mighty impressive (although that's a rather welcoming smile for so sharp a fish. ) The rocks look very good, so don't worry about how long they took. Their lighting and shading adds a good sense of depth, if you ask me.
I love the concept! Beautiful color harmony. The chromatic gray of the skin and the muted blues of the skin work together nicely. When I squint at the image, the torso almost seems to blend slightly with the background, leaving the striking dark hair and eyes to capture the viewer's eye. Nice work
Thank you so much @w@ You notice a lot I didn't even think about at the time, I wanted to paint my shark, or god knows what he is really, I don't know if you can see the kind of sharks that inspired him?
I love muted colors, so that should explain the colur use well. <:
Thank you so much again uwu You made my simple painting seem all that more valuable to me.
