:> This one was definitely a fun one to experiment with, and I'm pleased to hear that it looks like it could have been plucked from an animated piece! Most folks who do screenshots like that typically add noise pixellation to haze the image a tad.
And he did very much enjoy it! A lot of the scheme was pulled from his original palettes for the character.
It looks like you paused an animated feature and if I hit unpause it will keep moving.. thats hard to do!
It has a nice cool colorscheme thats pleasing to the eyes.. and I really hope the person you drew this for loved it.
