OK, I heavily re-did much of the model, keeping in mind all of the suggestions here - The scale of everything is driving me crazy, I beefed up parts of the limbs to look more muscular, and kept trying to adjust all the scaled parts here and there, not to mention also to match the head.
I've been re-scaling and adjusting the thing for so long that now its hard to tell what would look right.
On a positive note, I was able to glue the fingers together for this version, I'll save the high-detailed version for video clips for later.
