sounds like you have quite a lineup of guns to build. You clearly know how to build a solid rifle and have clean inletting skills. At the same time, every one of us strives for improvement, build to build. I'll tackle a couple areas where you could easily make progreas given the skills you already show here.
Lock panels: try for crispness.
The panels edges are rounded over. Better to have a flat where it is flat, meeting a nice sharp edge. This is getting rounded, maybe when you are in the finishing stage? Also the top edge of the lock panel on the sideplate side is too high. The stock should taper more from the tang down toward the sideplate, actually approximate the angle of the barrel flats much more.
Finish:
The stain looks a little flat, muddy may be too strong a term but there are no warm colors in it. The stain shows some lack of smoothness before it was applied- scratches are evident in some areas. There should not be scratches under the stain. If you are trying for an aging look, you want all the aging to happen on top of a nicely finished gun.
