Hey, Im pretty new at Pixel Art, and I was wondering if I could get some tips on how to shade. A friend of mine (Rasengan3004, I thinks he's made a few posts here) told me that I pixel shaded, which I now know is BAD, and I was wondering wheres the base place to pick a light source from? I am tempted to choose the TRC (Top Right Corner) and give it an Angle, but whenever I try it the shading on the head is a little weird, and I have a hard time picking colors, skin colors are hard IMO to pick out, so Help with that would be appreciated. (Also, if something seems off about my Icon, please let me know, I think its Proportions might be a little off, but this was my first REAL base icon, the other weren't that great)
