Well at the end of the year, I plan on modeling this thing up in Autocad. After taking in the advice given to me last time, I went back and revised my design- essentially replacing all "revoltech" like joints with ball joints. Feel free to give any 3D modeling tips or problems with my design to me. I haven't designed anything before, and I feel like I captured what I wanted to do with the design in this image.

I uploaded the original and the new for comparison.

I think this looks really cool.  

 

It looks pretty interesting...Your sketches really pulled me in with their detail.

From what little I know of design I will advise looking at the hip section; you might want to add some space between the thighs and torso to give the thighs space to rotate.

Also watch for the area where the balls meet the stems on your joints. An acute angle is more prone to snapping.

Third, you can have blocky shapes to be consistent with your aesthetic, but you may want to round off some corners where the joints are to aid movement.

I guess that's all I can think of for now.
