Want my two cents?
Looks NOTHING like the original. I'd give you alot of kudos if you did considering It's a massive triangle - and getting angled bricks in would be a massive pain in the ass. But that is beside the point.
Now , honestly , ask yourself
Does this:

Look ANYTHING like this:

as I've said earlier , I don't blame you for the top being incorrect. However , You could've probably made the azimuth arm angled ( Just put some ramps in and straight pieces and then gradually more ramps - it'll give it a nice arc ). You could've made the build a tad bigger since it seems really small and compact ,whereas in goldeneye it was massive and had tons of room to snipe and bombard from. A bit more care could be taken as the walkways in aren't even straight.
It's still a good build , it's just that there is a ton of potential that has been left unused.
