I started my replica of Lightning's Gunblade about 1 year ago, and never got to finish it.
It's actually a good thing, because since last year I've learned quite a few things. So in the end this gunblade looks much than it would have if I had finished it a year ago.
For the colors, I didn't want exactly the same colors as in the game : I wanted to give it a more realistic touch, a more aged looking.
I'm quite happy with the result although I'm sure I could do better ... I'll probably change the colors in the future ... one day ...
