@Cow - That's awesome, man! I like the sky, especially.
@JSimons - Cool pixel portrait. The black stuff near his face is a little weird - I think you can express it just using that gray / blue color that you have, which would make it a little less eye-grabbing.

Trying to get a feel for drawing women. Also trying to get a feel for pixelling at a larger size, and with colored outlines (usually, I use black for outlines). Not that simple, but I'm getting there.
EDIT: The outlines are colored here, they're just really dark. I think that lighter outlines tend to make characters 'fatter', though I'm probably just choosing my colors wrongly.
