Ok, Here's my critique, mate.

CONS: I don't like the design. There's just too much going on. I think if you get rid of that maze looking thing in the middle, it would be much better. That middle maze part looks like it should be it's own model, and not part of this one. Seems like you forced that in there just to fill space, and it doesn't need it.

PROS: The topology is clean, as always, and technically sound. You're one of those guys who takes pride in the wireframes, and it shows. As with all your models, I never see ngons, and rarely triangles.. The shapes are complex, and interesting. Makes me really want to look at the UV's, because how you managed to get a clean unwrap on some of those shapes is impressive.
