I think your carving skills are coming along, but your design is not that good, or in keeping with that of traditional rifles.
I mean this in the nicest way possible, but I would recommend that you do one of two things:
Finish your Kibler gun without carving, or:
Let the gun sit and learn the design/artistry of the old guns.
Carving it like your practice piece will diminish its value, and in six months, or a year, or two years, you will see what we mean by that. Kibler’s guns are beautiful as they are.
I know that all sounds harsh, but it is imparted with respect for you.
In the words of Jack Brooks, a master in this craft, a good design carved with only average skill will look great. A bad design carved very well still looks bad.
Study the old rifles, look through our library here and be critical of your designs. it will serve you well.
All the best,
Norm
