I think this image would have been greatly enhanced with a blue background. The white competes with the highlights, making the entire image washed out.
The wizard looks a little flat - perhaps the stright on lighting did this. A little more side lighting and it would add some depth I think. Good job with the placement on the background, but again, I think you could have cropped with the wizard to the left of the shot a little more to have him staring "into" the shot. Applying the "rule of thirds" here possibly would have made the image more interesting.
Love the figurine. It would have been a nice touch to place him in some grass or against some natural background. For me the white is too harsh especially with the brightness on the wizard.
