I'll second getting rid of the stand. I'm not a big fan of pens on stands 75% of the time. Sometimes it works, more often than not it don't... But more importantly, IMO 99.999% of the time, shooting strait at the clip is a bad idea. It has blocked a good bit of your pen's content, and is usually just a mass of highlights. It can look interesting, but not dead center in the pen. The same shot with the pen rotated 45 degrees in either direction would be much better...
The technical details (exposure, color balance, etc) are dead on, so some work on composition and you're looking good..
