Hi Jeff: You did not ask for suggestions or comments, but I will give some absolutely FREE of charge!!!
Your pictures are
HUGE!!! Maybe a little smaller...
Pen #1: The wood, the segmenting, the materials - GREAT! My only thought would be to have the top and bottom segmenting the same (i.e. Scallops - both top and bottom; or straight segments - both top and bottom). What you did is excellent, so this is just a thought to consider.
Pen #2: No suggestions - Looks GREAT!
Pen #3: Also No Suggestions - Looks fine as is!
These are very nice pens!!!
