I'm working on a 3D version of Blastoff. So far I've done his arm. Comments/suggestions are appreciated.

 

A little early to tell, but so far, it looks good with the finger joints (doesn't look like they'll clip). I could advice some tips on the elbow joint in that it's going to use the same joint mechanism that you've got going for the fingers.

Looks okay other than that. I'll need to take a good look at Blast Off again.

 

yeah, I made sure that no parts were clipping.

 

any other thoughts from the other 3D artists out there?

 

Seems like a good start. I'd say keep going with it  

 

A way to get modeling feedback would be to post screenshots of a wireframe and multiple views to get a better sense of proportions and polygonal topology.
