The outside looks great.
The inside banding needs work.
I would have run the vertical banding by the trigger guard in one piece so it is straight and aligned.
I would have mitered the top of that same piece to the horizontal angle. And all joints would have been cut tight, I might have even cut the piece at the bottom of the powder holder in at a point and mitered the vertical I talked about so it's seamless.
Just a little constructive criticism. It's a beautiful gun and it needs matching workmanship.
Please don't take it wrong, meant to offer some insight.
