That cocobolo looks really good! Try a more subdued background, it will make the pen stand out much more. Also, either you moved when taking the picture, or the camera was focusing on the rather busy background rather than the pen. I always use a tripod, and found that a fairly light, neutral gray cloth works best to emphasize the pen in the picture. There is a photograph forum here on the site which can be very helpful for improving your pictures.
I am a big fan of the Sierra and Sierra Vista, a slightly more rotund version.
