I was quite pleased how it turned out.
As you are a self confessed newcomer, may I offer some comment and criticism?
Its very well turned, you have avoided the temptation on this pen style to make it straight, and have incorporated a gently curve. The other extreme is to make it far too thick, ending up like some kind of medical probe. Take a caliper measurement of it and record it so that next time you make one of these you can refer to it. I don't measure mine anymore but do it by eye down to around 13.1mm (ends are 12.15mm). I can usually get it very very close without calipers, feel is sometimes a better guage than the eye. As for the wood, could be a multitiude, but as there is no grain to talk of and the colour could have been influenced by the finish that you put on it we could be guessing for an awful long time! The wood would not be my first choice if I'm honest, it's a bit insipid. George Watkins who posts as Cornucoppia on other websites and runs his website
Home (he makes blanks, ironically from wood and resin - take a look they are spectacular but expensive and not for slimlines!) told me something which has always stuck in my mind, lifes too short to turn crap wood.
