Thanks for taking my comments with grace[

You have the lighting too close to the sides of the tent in my experience, also the pen is too far forward with respect to the position of the lights.
The lighting should be aimed into the sides of the tent but not directly across from the pen or the other light. I like to have my prime light source aimed at the exposed side of the pen, to highlight it's features. The second light is set farther away, less intense with the increased distance and at an angle of about 45 degree's to the pen. Sometimes I difuse even the second light to reduce the balance between the prime and the second light. I also use a reflector white card across the front of my tent.
If you move your lights and set the pen deeper into your tent so you have light falling on it from two angled sources then you will also see less contrast in your images.
I am glad to see you use a tripod and I am guessing you also use the self timer, Good Ideas. [

It took me awhile to get some of my exposures right, no two pens photogragh the same way, but I document my methods and make notes and sometimes I get it right..[

Test a few lighting set ups and keep the camera exposure the same, if I can use a clock analogy, put the pen at 12 O'clock, set one light 8 O'clock and the other at 4 O'Clock, place the one at 4 O' Clock about twice the distance away from the pen as the one at 8 O'Clock , then start taking pictures moving the 4 O'Clock light closer till you see what you like......and also take a piece of white refelctor, paper will work and angle it into the pen filling the shadows...if that works, great, if not , well I tried..[

These are just my methods, I am not a pro nor do I pretend to be one...[:0]
