Chris, congratulations on a very fine build - especially if it's your first from a plank. To my eye, you have a very authentic looking rifle there.
There are a couple of things that I may have done a little differently, since you asked for input.
It may be just the photograph, but it appears that the lock is a little tail - down. This may have developed from setting the barrel a little too far toward the butt plate. Or it might be the look you were after too. I think I'd have increased the bend of the breech plug tang to take away some of the hump there. Here again, what you have is not necessarily incorrect. I really like the incised chips on the butt trap forming a track...very clever and well designed. I would have filed the edges of the butt plate, rounding the plate toward the stock, so that the edges there are thin. Likewise, you could thin the upper and lower molding on the lock's panel as well.
When you photograph, try to find a background that is anything but white. A white background under-exposes the object unless it's a close-up shot.
These are very minor things, and I sincerely think you've done an excellent job on your rifle. You must agree that there is no way you could have taken a precarved stock and achieved the look you got here. Now, make another.
