From the looks of the reflections, you're using a relatively small light, mainly from the front, right. What's important to remember when taking photos of shiny things is the "pool table geometry", "Angle of incidence equals angle of reflectance", and when you have very shiny things, you will see the surroundings in the photos.
Now small light sources make sharp shadows, and small highlights that fall off quickly. That is why you can see the shadow cutout above your pen, and the highlight on the nib end stops about 1/2 way in. A larger light source will soften the edge of the shadow and make the highlight spread out, and this can be done by placing some diffusion material between the pen and the light, but it IS going to reduce the brightness of the light. It's a tradeoff of quantity to quality...
The position of both the shadow and the highlight are directly related to where your lights are, so think of where you want them to be when you place your lights. If you want to show off the shiny smooth CA finish and quality plating, placing the light close (but diffused) and above the pen (slightly behind even) will give it that nice reflection along the upper edge of the body that really shows the finish.
If you're aiming to get on the main page, you're likely going to need to "dress your image" a bit, create a scene or setting that kicks it up a bit. This can often be just as important as the lighting/exposure. If you just want to see the pen, your shots are fine, but if you're looking to make a promotion image or a more appealing presentation, you'll need to do something more than lay the pen down on something and snap away. Even the ones with the pen stands could use something beyond the flat background. Contrast is always a good thing, so think about your pen, is it mostly dark or mostly light? Your "set" should contrast that. A black titanium ebony pen is not going to look good on a dark background, and a chrome holly pen will not look good on a white background. One background rarely will work for all pens, and while I rarely see people using pure black, many people try to use all white, and I think it is rarely a good thing. Point and shoot cameras are not going to want to see all that white, so you're going to get dull lifeless photos (from a lighting/exposure perspective).
Sorry, this post got a bit more involved than I had planned, and (lucky for you folks...) I've got to get going before I go off on another tangent....
Overall your photos look great from a "here's a pen" perspective (nothing wrong with that, that's about all I do at the moment with mine...)
