I like getting Icon tasks because often times they can turn into little paintings and give me excuses to to draw props and do little studies, They don't have to be super polished since they are tiny icons. These are a few of the ones I did for World of Warcraft: Legion.
Some of the fish icons were snagged from Ryan Metcalf concepts and painted over. (bottom 2 and 3rd from the bottom)
Also the Coy fish I painted over a Tyson Murphy model. Wanted to credit those dudes. :)
