Maybe it's just because this is the first picture of it close up, but it looks a little plain to me.
If I were you I'd at least show some indication of the details that are missing in the Pepakura model... the patterns on the gauntlets, the details on the chestpiece, etc. Maybe just some black paint outlines to show the missing design elements might help.
It looks great by all means, but overall it's starting to look too uniform.... no pun intended.
Nice job on the BR byt he way... that happened fast!
It's pretty dirty though, maybe you should wash it. ;-)
