3D prop the next

Following the gun i have already made for this assignment, the bigger part of the grade (90%) will be based on this larger model, with diorama. As stated earlier in the blog, i have permission from Scifiartist to make junk robot 2 based on his original concept art.
The model is being created by forming the main parts of the body from basic primitives, then extruding and transforming the verts and edges to create the shape of junk robot while generating the fewest polygons as possible. As he is quite rounded in his shape, my 10,000 tri limit is dwindling, but at this point i'm still under 4000 and should be able to generate alot of the detail with textures. Here is junk robot at the moment, just a stump of an arm and the diorama to go.

And the original image for comparrison.
