Great color choices... Most people associate primary colors like blue, red and yellow with color bursts. Image quality is generally good but the DOF may be a bit too shallow. A couple silver balls on the bottom and right look slightly out of focus. Taking at a narrower f/stop would fix that. The star is not quite "level" and should be straightened much like a horizon would be straightened.
Wow! (donning my sunglasses) Now THAT is a burst of color! No doubt. Personally I'm not crazy about the purple in the border since it doesn't appear in the photo, but cool image (and object). A bit more overall sharpness and I would have scored this higher. 7
Putting this on a red background doesn't really "offset" the object from its surroundings. would have been better on a black or white background in the context of this challenge... that's my interpretation anyway.
