Just a quick update:

I tried to smooth some inner lines, changed the shoes based on Doppelganger's edit and changed the kitty's face (for better or worse).
Atnas: I'll play with the feet. Just to be sure, are you talking about flatness from a lack of shading, or the flatness of the soles? I'm thinking it's the latter, and if it's not, Doppleganger's edit might've helped the problem. Otherwise, well... I tried un-flattening the soles with little success, so like I said, I'll play with it and see what happens. The arm was intentional, though, like Indigo said. it was a conscious choice so I guess it comes down to a matter of taste.
Indigo: I did a little more aa'ing, but I'm not sure if I'm understanding your meaning. You mean I should more heavily aa the inner-outlines, (like the inner curve of the arm, the jeans' pockets, etc.), or like, the inside of the outlines (outer curve of the arm, jeans contours, etc.). Anyway, again I jumped to the conclusion that you meant the latter, and that's what I tried for.
Dopplegagner: Worry not, my friend. I'm back for good, and ready to produce a vast catalogue of new pixels ...or something like that. I dunno, I'll probably get bored in a bit and have sandwiches instead. Anyway...

Yeah. I've been away from pixelling for a while, obviously, and like I said, I think it shows. That said though, the lack of AA here was intentional for the most part, especially concerning the contours. I'm trying to get away from my reliance on outer AA, and I'm thinking that when it's done, this one'll have a transparent background, so... As for the shoes though, thanks

. I was messing around with the palette, trying to find a decent way to add some depth to them and, for some reason, ignored the gray.
Atnas (again): Heh, I was going to mention that the spots would probably be ok once I tranperificated the background, but then you posted what you posted, so...

Thanks guys <3
