Nice neat work. A better photo would help a lot - try using a piece of grey cardboard as your backdrop. That way you can set the colour balance using the cardboard and avoid the slight warm tint that seems to be in this photo. If you can use a couple of light sources you'll get more even lighting which will help as well.
The base could use a little more work. It's a bit bright which distracts from the mini itself, and the flock might look better painted.
Keep up the good work!
