Suspend the fighter from a tree with black thread and shoot at an angle so that you can see the stars. Get back far enough that you have to use the zoom so you get plenty of Depth of Field. Light it with a porch light or flashlight and do not use flash. Make sure there is no wind to avoid motion trails.
Flash is too harsh. Try some indirect or diffused lighting. Try not to light your background. The wrinkles in the cloth make it appear cheap. Try different angles on your subject, dead on from the left, right, top, bottom, front or back is never gonna look as good as a diagonal view. Try not to stick your subject smack dab in the middle. Look up "rule of thirds".
Great focus and dof. Contrast good. The composition is somewhat boring to me. Doing something other than centering the subject in the center may have helped this shot to pull me in a little.
The different colored legos make nice, distinct blacks and whites, with a couple of gray shades between. This could be a good subject, but I'd like to see it from an angle that's more interesting. Maybe turned toward the camera, but on a bit of an angle sot hat the pilot's face showed. You wouldn't necessarily have to include all of the ship in the image - might make it look less toylike. The composition, as it is, is very static and centered - not what you want for your starfighter. Whites seem blown out, as well.
Lego ships are cool! Good job with the backgorund and the lighting on this photo... the slight wrinkles in the background could possibly have been smoothed out a liltle for a minor improvement... good job!
