Hey Drazzke, welcome to Pixelation!
I am not exactly sure what it is. I guess it is an Unsure Robot Guy. (Or at least, thats what I think he looks like).
This is a bit of a danger sign, and an easy trap for beginners to fall into. It's not a huge deal or anything as long as you are aware of where this sort of thing can lead! Basically there is a bit of a fine line between just doodling for fun and working out the goal of the image as you go (which almost all artists do to some extent) and attempting to draw one thing, failing, and trying to pass it off as another, rather than addressing the flaws and working to correct them. I'm guessing this piece falls more in the former, rather than the latter, so I wouldn't worry about it TOO much. A good habit to get into early is to start out with a goal of some sort and to see it through even if you're pretty unhappy with where it is headed; you'll find I think that you will learn a lot more from doing it wrong, and examining it with a real critical eye, than you will from doing it right.
Anyways, I hope that made sense! I agree with infinity's basic critique - you've used a lot of colors and there is nothing about your characters silhouette or pose that really says "Robot." Also, robot or not, this is a strange and essentially mirrored pose. You may find it easier to communicate more character and attitude with a more dynamic pose and perspective!
Good luck
