You know.... It's not a bad MOC, no where near close to that.
However: I feel it has an issue many oversized MOCs seem to have. (Main reason why I don't like attempting this scale) But it just seems like the only aspect that's noteworthy is it's really large.
As some others have mentioned, the armor coverage isn't that great, and has a lot of clashing textures.
But it's still a good MOC! I would say possibly adding a play feature (or whatever) to make it more appealing.
