can you take a picture of your whole light box? I dont think you're using the backgrounds correctly. You shouldn't have any seams in the back because the backdrop should be smooth.

Your pictures look nice but they could use a little work.

- color balance: whites should be white and blacks should be black
- cropping pictures to make dynamic, flowing and interesting compositions
- your backgrounds shouldn't be distracting, there shouldn't be any wrinkles or differently colored patches or pieces of lint.

I went to college for photography so I tend to be pretty critical of images so dont take any of this personally, take it as tips to help you make better photos!
