For photographing pens, turn it so that it is almost horizontal. At the close distances needed for shooting pens, the depth of field is extremely shallow. Having it almost horizontal puts all parts of the pen about the same distance from the sensor. It also eliminates a lot of the distortion you can get when shooting them the way you did, like the lower barrel looking bigger than the upper barrel. The entire picture looks a hair out of focus to me.
That said, it's a great blank, but it looks like the wood is under-sized at the clip ring. This could be due to distortion because of the angle of the pen.
