Peter glad you asked for a critique the top two similar views have different lighting the first flatter than the second and third to me there is a little more magic in the last two every light gives a shadow etc. Believing as I do showing our pens easily, repeatedly and enjoying the results thanks for showing.The pen is one that looks as good apart as together.
When I made my first one I found making it that the timber thickness is fairly fragile in thickness the instructions most confusing depending on how the parts arrive partially assembled or one at a time.The top drifts off easily allowing individual selection or matching timber etc or a jewel etc. I admire your turning and finish with this pen combining with character.
Kind regards Peter.
