I like this design! I find it difficult to draw multi-limbed characters--like what to do with the arms when they're doing something. But I like how you have each arm doing something distinct without being messy. The perspective is good as well! that's a difficult thing to do, especially with a unique character fitting in with the environment.

As far as critique? I'd say add some variation to the line width. With the lines being the same thickness throughout the picture, the subject and environment blend in somewhat. Other than that, I say this is a great picture!
