amazing!!! i love how you interpreted the @ sign! however, if you like more of an "adobe" or "hand drawn" look, you're in luck! if you take the outline, double it, and put it behind the fill layer, you can change the outline width without changing the actual shape of the sprite!! yes, it makes shading somewhat a pain, but it can be applied to any sprite!!
