I'd have done anything I could to make this picture bigger, but to keep the bulb seem small. Maybe just put a gigantic black border around it to isolate it.
The size of the photo itself hurt this photo for me. You can have up to 640 pixals on the longest side and up to 150 kb total. You lost a lot more of your shot then you needed to by trimming down this small.
Generaly larger pics do better on DPC. I think you have a well lighted and technically sound shot. The lamp appears too centered for continuous viewing, so you might try shifting it to one side ot the other to invoke more interest. 5
Looks like lightbulb snapshot, no special effect, no cool lighting,no interesting objects :-(,and picture is too small,next time make it biger up to 150 kb!
Needs to be bigger - you can increase your jpeg compression to make the file size smaller while retaining the number of pixels in the image (you can go up to 640 pixels on a side).
if the light from the bulb could be dimmed, then couple that with a long exposure from the camera, it would create a much softer image? anyway for this image, the cropping is not exactly interesting.
