Well, the fact that you threw in an army of Feed Me's gave me no choice but to review this.
Some of the foreshortening is over the top, for example Tessa's left eye should be about the same as the other since they're both in the same level of depth. The hammer handle looks especially extreme. Tessa's feet are farther apart yet they both seem to be the same height, looks like her thighs are causing this problem. That's the major stuff.
The rest is pretty good, the colors are balanced, the expressions are interesting and varied, and the focus is very well defined. Just gotta work on your sketch a bit longer.
