For your first steampunk this isn't bad, from what I can see of the genre. However, I agree with previous commenters. However, I will say that your use of the dark green contrasted nicely with the brown. With some work that color scheme has a lot of promise.

Awesome! I'm not really a fan of regular SW, (Some are cool though) but I really like the steampunk SW MOC's. You should join the group that me and my friend made: http://mocpages.com/group.php/16901
