Welcome Sdaj, and Congratulations, on an Incredible First Pen.
Excellent Choice of Blank, Beautifully Turned, though the Diameter at the Center Band, looks a little under size for the Band.
This will just take a little Experience, to get the Confidence to identify and learn how to determine, how much to leave for Finishing.
I suggest that you keep this pen, and use it the coming weeks, months, years to monitor your progress.
Congratulations, I would have been proud if my First Pen, was as good as yours.
I look forward to seeing more of your work.
Brian.
