Your fit and finish are really good. The only thing I would have done differently would be to use some more "exciting" woods on these kits (with the exception of the first, because of the filigree). Your workmanship is certainly good! Just my $.02.
I have seen a CA finish on a pen, I like how it looks, but the problem is that when you hold it, you cannot feel the pen, you feel the CA. but that is my opinion.
I appreciate your honesty guys, especially coming from other penturners
