In all fairness and in my own experience, whenever one of mine is rejected and it's for technical reasons, I always recieve another e-mail telling me what went wrong. I can testify for WOM and Snowman but there must be others. Do they all do the same?
Jazzilady, the bottom line is, you have some wonderful works. At the begining I started deleting those that were rejected but I stopped. Do you have a Gallery at Deviant Art? You can always see what others think of your works.
Keep on and let your spirit be your guide (gut feelings)
