OK, STOP making new threads for stuff like this if you have a thread on the first page in the forum already. I merged the threads, and if you pull this again I will give you a strike.
Also, there is not much to comment on. It's a square with eyes and mouth/nose(?) and some rather bad beveled shading. I am sorry if I sound harsh, but I really think that you should be doing some fundamental practise in drawing and not pixelart. Sketch basic shapes like spheres, cylinders, cones, cubes and what not, and the go on sketching stuff you see lying around in your room, stuff outside, people whatever.
I know this is a really generic crit, but I think you really need to do that if you wanna get anywhere with your art.
