Ensellitis has a free hosting service for pixel artists, and I think he's still accepting requests. Here's the related topic over at pixeljoint. You get good bandwidth, it's free, and the URL is http://*.ensellitis.com, not really that ugly.

I think this is very good for a start, but it has a lot of problems with lines. I suggest you read up on perspective (it's not really that hard, you just have to know what you're doing) and rework the lines so the feet are more similar in size and shape and so the legs are fixed: right now they look like you drew in the feet and body then just connected them to the legs with some bendy things that're like the ref's legs.

You could really benefit from looking more at the reference; you would add a lot to the piece by adding the little details on the legs.

I do like the eyes, though, they look very crisp. Unfortunatelky, they, too, have perspective issues. You'll want to make the closer one larger as a start and you'll probably want to skew them into perspective if they're not directly facing the viewer. This has a lot of potential and I'd love to see something great come of it!

I was tempted to say something witty, spiteful, and undoubtedly scarring, but I've let you off with a link.

Still, nothing would have arms that are collectively as thick as its torso and your ear-things would show bone/hard supportive tissue along with muscle or they would bend downwards. You would do well to better show the curvature of the face and the crack in it rather than it just being an amorphous thing with a slit in it. Another thing, you hint as to a neck, but it would have to be something thin and flat, but you don't really show that to be the case. I guess the character would work better if it was defined more in a more natural pose before you made this portrait view of it.
