Hey, I like this. 
Here's an edit; I just thought you might want to get rid of those black outlines and get some AA (too much ? :x). Minor changes on colors too:

Your version -> My edit
In my opinion the black outlines give this a really not finished feeling. Might just be me though.
hey. thanks for comments and checking this out.
i keep the black outlines, it is kind of a design decision and the game i've been thinking has z-depth and there will be items overlapping the character and i think it is good to keep the black colour to define edges of playable elements. might do some lightening of the inner black lines.
i like your more saturarted colours, colours have been also in a kind of mock-ups.
and antialising, maybe something in between.
thanks!
