Actually he's probably not grumpy, that's just how his face looks.
This is for the weekly challenge and I pixeled it using GIMP over a few hours. I tried to keep the color count fairly low although I did allow my self quite a lot of blues. Also this is the first thing I've dithered in a while and also probably the biggest bit of pixel art I've ever made that wasn't a full tileset. It was pretty good practise. I imagine with more time I could get it looking a bit better but I'm pretty tired so that will do. ;)
