Ah ok I see, yeah it does suck how expensive art can be. There is always pencil and paper, but I know that's not as sexy as paint or digital. Do you have a scanner or a decent camera? We have the ot creativity thread and the anatomy thread here that might be more useful to you. That way you wouldn't have to be pigeonholed into doing pixel art when you'd rather be doing art art! I'm a fine artist myself, and many members here are pretty skilled in the more illustrative departments, so you're not alone in your love of stuff other than pixels.
Also, it might take some digging, but if pixel technique is not your end goal, and you don't have a tablet to easily digitize your own drawings, we have a line art thread somewhere where you could color other people's already pixeled lines and the focus could be more about color, which is more generally useful.
For what could be improved on the piece, it depends on what you're going for. Right now it's symmetry and lack of perspective makes it look like a design motif. Is that what you're going for? If not, you might have to scale things up a bit so that you could create in a more representational manner. There is some banding going on in the machinery thing, and there's some things that could be done to possibly make the golems read better, but it would all be a matter of a few shifted pixels; not really a road one needs to go down if you don't care too much for pixel art.
edit: also a little blurb that may or may not be helpful on attitudes toward critique. Artist's MUST be thick skinned to improve and be successful. But it's just that, the skin. On the inside most of us are all soft and gooey and sensitive, artists almost have to be, because our passion relies on our ability to sense and perceive the world around us. Even non personal critique can and will hurt because our work is an extension of ourselves. So while your freaking out, going nuts, etc might be a bit extreme given your disorder(s) the feelings behind it are something that all artists get, and it's totally ok. Get that out there, and then later, come back when you're in a place where you can see the points objectively and learn from them ( Easier said than done, of course).
