Interesting MOC, interesting indeed. I got a few things to say, so I am going to do this Pros and Cons style.
The size - I'm always a fan of bigger MOCs.
It looks imposing - The MOC has an imposing look. I would not want to run into him in a dark alley.
He looks solid - The MOC looks like it is solid. No unnecessary gaps or holes to be seen.
It looks cluttered - This MOC looks very cluttered. It's hard to tell what is going on here. It's also kind of hard to tell what this MOC looks like.
The color scheme is a mess - The gold is completely fine. It's just all the other stuff like white, ice blue, neon blue, and bright red.
The CCBS - There is not enough. I suggest finding some way to either incorporate more or replace those parts with technic.
He looks top heavy - Yeah... he looks a little top heavy. The legs look strong, but I've noticed that the MOC has it's legs bent.
And I know what you are probably going to say: It's in his story. Fair enough, buuut...that excuse only goes so far (trust me, I know from experience).
Ultimately I give this MOC a 6/10
