I think you are going on the right track. The next few things you should address is the "pipe-legs", as Stwelin so elegantly put, and the current lack of depth, which I tried to illustrate with my shitty edit.
If you are feeling up to making the the best it could be, you should look into making the post a bit more dynamic rather than statue-esque as it is now...I would suggest something sneaky...may a foot up...tail straight.....just opinion though: you go where ever you want with this.
This piece is improving a truck load, and great work so far! Keep pixelling!
