Crate, "folded and unfolded." I messed with perspective but I don't know if I got it right and the horizon may be in the wrong place.

The hat makes no sense. Is it one of those knitted winter hats (I can't believe I forgot what they're called. Ski hats?) or is it a baseball cap? I have a little quick edit to show what you need to do to show which type of hat it is:

I think the main issues here are flatness, high saturation, and antialiasing issues. In some areas, you do antialiasing that seems perfect, and I have no problem with (bottom of parrot's upper beak), while you only aa one pixel long in places where you need more. A good rule of thumb is halfway between the colors, halfway down the line it's aaing. Also it messes the look up if you only aa on one side of the line, but I can hopefully attribute that to time constraints.

The issue of flatness arises from the lack of consistent shadows and highlights. You have nce highlights in some pieces and then you don't do anything to show where light wouldn't hit. In other pieces, the opposite is true.

As for the saturation, what's the monitor and app like? Does the program have limitations or the monitor bad settings, or was it just that you couldn't be bothered?

This is looking goodso far, and it seems to fit the 'style' you've gotten started wiyth your avatar, but it looks somewhat pillowshaded. Try making another version with a lightsource in an extreme corner. As for the arms, don't give them outlines. Use a few pixels of the darkest color on the shadowed edge, but as bits get smaller, so do the amounts of pixels of each color. Try giving him really long fingers like a gecko or adding a bionic claw maybe.
