Good Luck Reza. Looks like you took good care to get a nice fit for your body. Definitely aiming for Centurion from the get go, which is awesome.
Aside from Phil's comments above for tweaks, I have one question about the belt, it seems to be stretching around your body rather than wrapping, noticeable in your side profile photo for your left side when you are detailing your 6 split rivets. . Also in the shot where the belt is by itself, it looks bunched up... it the belt elastic?
also, out of curiosity, who made your neck seal, I have not seen one with that shine before..i think I am starting to like it!
Once more good luck sir...though I don; think you'll need much luck here!
