In the first picture, I see two light sources...maybe your flash and maybe a light that was on the in the house? The white balance looks off. This is caused by incandescent lighting. Even the newer "whiter" light bulbs are still pretty yellow. I would maybe turn that second light off and set up some white foam core around to bounce the flash off of.
In the second picture, it looks like you had some pretty "harsh" lighting. Looks like you shot directly down from overhead. Preferably, if you can buy or build one, shoot in a light tent through the opening in the front cover. This will also get rid of your reflection as seen in both images. Or at minimum, get some sort of diffuser on that flash. If it's on-cameral flash, I usually put some wax paper over the flash. This will soften and disperse the flash and soften the shadows. If it's a flash head attached to the camera, there's some pretty affordable ready made diffusers that will do an excellent job.
BTW, neither pic is bad and the pen is beautiful. Just thought I'd throw in my $.02 (which, after taxes, is really only worth $.005)
