User blog:Badoop/Arm design!

First off, further apologies for lack of posts. I've been trying to do school, art, animation, and a social life all at the same time, and it's left me very little time to contribute to this site, which kinda sucks. At this point, I've come up with the idea to sort of post design ideas as they come instead of trying to compile one huge thing. Expect more of that.

Anyways, I think I've figured out an arm design that allows for an arm to have fingers while being able to grab stuff without changing any part of the hand (like, say, an extension to the hand that a weapon can attach to). For a lot of the hands-with-fingers designs I've seen, they either: Because of this, I made this:
 * 1) Look really good but can't grab anything at all
 * 2) Look really good but the way in which they were made make it so you can't really hold a weapon without adding something to the design so weapons can be held

Forgive me if this is no original idea, but I haven't really seen it in any other MOCs but mine and I came up with it on my own, so at this point I assume that it is. I don't have the right pieces to make a thumb, but I'm fairly sure it'd be easy.

With all that said, what do you guys think? Any improvements I should try to make? any mistakes I should rectify? Is this not   o r i g i n a l    c o n t e n t  ? Tell me in the comments below!
