Here's an EVA Spartan done Halo Reach style. I noticed Emile had a skull carved into his helmet, but other than that it was a regular EVA. So I removed the skull, swapped some body armor around, and gave this EVA a whole new paint job based on earlier art. A special two-tone metallic face shield painting and he was done, ready to take on the Covenant!

I did the same thing. Original project was to sand down the skull, and it worked pretty good up until I discovered I had used the wrong paint for the actual base helmet armor himself. Enamel.... A terrible story, as it actually looked pretty good. Success for you!
