i dont get how how the legs and face are in a different perspective 
i dont really like your color choice
i really like my choice of colors and perspective.
Hey man;
Hope this illustrates in a better way; check the big guys with the green arrow; they both have fixed perspective.
In one, you have the eyes that acomodate the legs perspective, and the other is the exact opossite (the sideview)

I was just proposing some alternatives on your colour choises, giving emphasis on the slight hue variation, wich as you can see, does make a piece more visually appealing, you can, however (and thats the point) check how its done and pick your own colours with hue variation.
The colours are indeed brigther, but thats not what im trying to show you, but the contrast between them; if you have 2 shades, and one is practically the same as the other, the shading wont be noticable, and speaking in pixel art terms, its a wasted colour.
Now, probably you dont like the changes that i made to your char, BUT, look at them, check the antialising that i applied, it makes the char rounder; check the little highlight done at the bottom, wich enriches the character, check the shadows, the little "bump/lip" that now the char has, all of this take it study it, and apply as you see fit in your own way.
