Oh crap, this comment got buried under other comments. I've been busy lately. Sorry.
I agree that the lower legs could use some work. Over all he could probably use a second looking at now that I have some perspective on the MOC.
I'm glad you like him. His benevolent nature I think won most people over, even if he's not the most well built MOC. I wasn't exactly going for that though. I was wanting to capture his character. Now that I know I've done that, I'll take your advice and see what I can do to improve. I think you'd be surprised what's available in his color scheme. Brown and tan were used in bionicle, but moreso in system which he's largely made of.
