I agree with Ratius, better pics would help show off the mini. Here are a couple unsolicited tips:
- Use a backdrop. Items in the background distract from the mini. I use these:

Just print them out and you're good to go
-Never use the flash on your camera when photographing minis. Have a light above your model and one in front. I use the lamps I paint with.
- Crop the pics. You only want to show the model and a it of background behind it. I usually use in the 600 - 800 pixel range for width and height.
Your model can only looks as good as the pictures to people seeing it online, spend some time on them to show off your work!
