Hi Barry,
Overall I like your designs, but I think a few tweeks will improve them.
I think the wrist pattern on the lock side looks pretty good. You might want to tweek the downward facing C-scroll. The middle and right side look a little off. Maybe thin the middle a little and/or add a small fern tendril?
On the pattern forward of the cheek piece, I think the rear volute needs to be better related to the arc of the front of the cheek piece. The carving needs to flow out of the cheek piece.
In the pattern behind the cheek piece, the c-scrolls, lines and volutes need to be smoothed. Gary Brumfield told me some things that helped my carving. Fern tendrils, scrolls, etc. should gradually increase in width, not get wider then narrower. Volutes should gradually get tighter, or gradually open up, but should not both, it results in "elbows". Study the scrolls and tendrils on the back of a one dollar bill.
This is gonna be one fine gun.
