Based on a conversation with featherhead, if I had a "fish-sona", I'd end up being a rather large rainbow trout... who is ironically colorblind.
Going to have to color it in one of these days, but I felt like sharing the sketch of the fattest fish I've drawn XD
Addendum: In my other gallery, I have this one listed as "Twitter Sketch 45", but I have no idea where Sketches 43 and 44 went, so I think it might be a typo...
