This looks VERY good! I think you did an excellent job with this set! Love how you put together that undersuit, too. Um...I don't want you to take this the wrong way or anything, 'cause...well, I agree with the codpiece being too large. Compared to the rest of the armour, it really stands out. Or it needs to sit up much higher on your waist. You could try cutting it down then reattaching it if it's too big back-to-front, too.
Anyway other than the codpiece standing out in size, I like it. It's a trés magnificent ensemble.
