Tack sharp and noiseless image
If you constantly get rejections for blurred and noisy images, why not try your hand at Vectors. It can be a pain to learn but once you have gotten the basics you can really do wonderful things with Vectors. Almost lifelike 3d stuff.
Here's a sample of what you can do with an old blurred photo and some time to kill. Took me around 20 minutes to do it.
