Impressive work. If you plan on doing a whole lot more detail sanding and polishing in a tiny, confined space, I cannot recommend these things enough:

I pop into this forum once a year to run the Halloween costume contest. THIS is fantastic. As others have said you even look like Samus with the helmet off! What I like most is that you took the added effort that many skip and finished these 3D prints so that they were truly high grade. Well done.
I highly recommend you enter this year! http://www.therpf.com/f24/rpf-2014-halloween-costume-contest-225751/
Congrats on a fantastic costume! :thumbsup
Oh yeah I almost forgot about the contest! Totally going to. Can I wear part of my costume for the proof photo? It's so hard to get fully dressed up as Samus, haha!
