Have you tried taking pictures of your models in various environments and lighting sets? Try this:
Your kitchen/wargaming room with the light on.
1. Put the model on the table, take a picture.
2. Put the model on the table, turn the light off, take a picture.
3. Model on the table, white computer paper underneath, light off.
4. Model on the table, white computer paper underneath, light on.
5. These are presuming that you have blinds and windows - try these shots with your blinds both open and shut.
6. Put a black shirt / felt underneath your model, repeat pictures.
The worst is taking a picture of a model on a surface with a gloss finish. ><
Compare all the pictures and see which one you like the most.
