It's not great, but it is better than some helmets out there. My main issue with it is that it is elongated from front to back like the Rubies helmet. That is no fault of Brian's as he did a good job with the conversion. It is something that really cannot be fixed though. As for 501st acceptance, who knows? Right now there are some weird things going on with the clone approval process from what I've heard.
What you need to fix though is the visor area. You need to round those corners.
