Quoting A. A. (A.K.A Noname)
Good work. Try to add some red parts as the organs he still has. (if you can). With every Bionicle MOC you make, you always manage to put the right System brick in the right place.
I've done this and improved him some more so if I remember in my next Bioicle Style model I'll put some pics at the end just for you;)
