You did a great job in this one! Though there are two noticeable things I should point out The left eye (on the right side of the paper) is a bit too high up and the lower body is smaller than the upper. The stomach should be a bit longer along with the legs. If I were at home I'd find some examples and red line your piece for you. (hopefully I can do that later) But you've brought to life this character, I assume, you're playing at and added personality to a cluster of small pixels! That's really fantastic and you should continue to draw out those things.
