Pros:

-Well done and detailed
-No glitches to be reported
-Detailed Visor
-Looks very close to the actual Master Chief
-Has FPS arms! 

Cons:

-None, although I could say his armor might be able to be modified to be slightly more clear, or fps arms to be a bit more detailed. But this is nothing. I extremely recommend this if you're reading the reviews.

Conclusion:

I'd like to have coach stay with this skin. Its absolutely amazing! You won't be disappointed for any Halo fans out there XD
