That is an extremely nice pep helmet you have there.
If I may add one artistic criticism though? The silver marks on it that represent the "battle damage" might look a bit more...natural? if you were to add to them the general sort of wear and tear that might be associated with wearing a helmet...adam has a great painting technique that shows this extremely well.
I used JediFraz? version of pep armor. (The one in the sticky)
Also, the paint job was kind of rushed before Halloween, plus it was kinda hard to paint right behind my dorm... I will probably sand down everything and re-bondo the outside for more detail. Also, I need to bondo and detail all the other amour as well.
