Many thanks.
I will keep thinking of new ideas and upload if other options. :)
It good to see a CH (contest holder) that understands the whole RGB / CMYK issue. It has been a topic of some contention around the forums here lately. Unfortunately, most people don't understand that CMYK to RGB is fine, but RGB to CMYK can be disastrous. It's can see how most people don't know (or should even care) about the difference, but as professional designer, it is our duty to be sure the client purchases something that they can use. Because I also run a printing business, I see this on a daily bases. A client comes to me saying that their last printer did a horrible job. Well, as you know, it was not the printer, it's the file and unfortunately there is no way anyone will give the client the results they see on their screens. Lately the site has been trying to remedy these issues, because it's become somewhat of a problem.
Anyway, if there is anything that occurs to you, even if you would like a change on a whim (just to see what it looks like), just ask. That's what we're here for. :)
Thanks again.
