I drew a RPG character. My very first.

i think you mean powers of 2

See at first I thought you were right for correcting him... then I realized his mistake was actually correct, even for reasons he didn't anticipate. When you're using a 320x200 screen, you cannot easily do 16x16 tiles unless you plan on saving some space on the top or bottom for stats. But if you're pro and want the stats to overlap the game in some cool way, you can do 20x20, which would be multiples of 4, and still get the whole screen filled with tiles like a pro.
