Dang, I really like this guy! I love the poses you put him into, and for some reason I really like those hooks on the feet.
The only downfalls of this guy, I think, are the slightly cluttered textures and the hands. As with most MOCs using the old system sometimes the many various textures can get mixed up, and I'm not entirely sure where you could go about fixing it. As for the hands, I feel that they look somewhat messy, large and incomplete; I feel like they need something to cover up the exposed technic.
Anyway, in spite of these flaws I still love this thing.
