The thing you want to avoid with volutes if you can, is parallel sides for any distance, Generally, they tend to look a little better if the relationships are always changing. Many of yours get fatter toward their heads (which looks nice) but a few of them are pretty parallel through the middle of their stalks and toward the base. You want to avoid a lot of repetition, (and yours does not) which can make a design sort of boring. On my last gun each major carving design took me a week to draw and be satisfied with it before I took a chisel to it, and even then it took 3 weeks to cut in and be happy with it.
