Nice job Tony.. You made the right start by leap-frogging the slim line and starting out with the cigar. I think more new turners should start out with this kit as the price is not much more, yet the pen is light years ahead of the slimlines.
The first one looks just about perfect in form, there might be a "sharp blank vs rounded coupler" issue due to the kit design itself, but not an error on your part. If you have this sharp line, I suggest swapping a smaller bushing at that end to "round over" the edge a bit when you sand it and you will find that the curve fits better. When I made new cigar bushings on my lathe I turned that one smaller to better fit the pen. I turn with calipers anyway, but having a bushing that is a bit too big makes it hard to turn the blank down properly.
Very nice set for you first, or heck, even after quite a few pens to be honest!
