I love your castings, that is a super looking pen![]
The object that you are using to hold the pen up is very distracting, although it is a nice object in its own right, it really takes your eye off the pen![8D]
Pen looks good, I agree on the background it takes away from the object of focus as well as the reflection off it changes the look of the pen. The section leading up to the nib looks two toned from the reflection.
