Well, a spartan is 7 feet tall and they are a tad below the elite's neckline.
It seems from the picture that you would be at chest height, maybe a bit smaller because the elite is farther in the background, so add 1.5 feet (Assuming you are 5 foot 6) to get the spartan height and that would put it at the bottom of the head about. So I'd say it is only about 6-12 inches off, but then again it could be a smaller elite and even if it was full size it would probably be too tall to fit in a room. However I may be completely wrong, and probably am. Even so, who cares, it's big like an elite and I don't think anyone would be able to notice any scaling issues as they are being blinded by the awesomeness.
Tl;dr It looks almost perfect size and is too awesome for anyone to notice that it is too big or too small.
I applaud you for having the patience to pep that whole thing and still have it come out as clean as it did.
Awesome Noble 6 helmet too, do you have a progress thread for it?
Lastly, out of curiosity, what does that tattoo on your arm say?
Oh and nice shirt, I used to listen to them 24/7.
