Oh, and Draco's edit is really bad, don't pay attention to it...
This is the kinda crap that gets you reprimanded, Gil, so the next time you get warned by the admins, you won't have to ask if you're "
really that much of an ass," because I'll tell you right now, you are. These comments are completely unnecessary, and only discourage members.
Zee, I think that one thing in general to work on is your use of the palette. For example the eyes on the alien... hooker, you use 2 shades that are almost completely identical, yet you only use 3 shades for the skin leaving it really harshly shaded. I'd suggest maybe bumping the colour count up to 4, 5, or even 6 for the skin and smooth out the basic form you have outlined.
