Photo not accepted

Please not also that the retro look may get your assets refused. You can easily aply a retro look filter, but you cannot bring back the full colour asset. So, you should let the buyer decide, how they want to have the asset. 

From a quality point of view: the retro look is is an error, that photographs get, because of colour fading. A similar effect are scratches, light leaks or lens errors. You should never simulate these. 

It's very important that you zoom in to at least 100% and inspect every area of every image from corner to corner. Images that look okay in small size often have many problems when inspected closely. If you can't fix the problems by editing the image, discard it and start over.
