His right arm seems very awkward in a couple of shots, like it's barely hanging on. The freehand is excellent work, though.
I like the battle damage and weathering, although the scratches look too uniform, which takes some of the believability away. The depth you've put into the shading is very nice, though.
The base isn't bad, but it doesn't jump out as great to me.
I agree with the previous comment on the lack of depth in your chainfist.
I good effort overall. I like it. :)
Awesome model. Would've rated higher but I find the post, mixed with the basing to be very distracting. It looks like he's about to topple down some steps because he's too busy looking at his hand. I also think your metals could do with some more work, less sharp highlights with more depth to the shades on larger areas like the chainfist.
