Hi bluehooloovo, thank you for your reply. Yes, I saved it as a psd (and possibly a jpg) while I was working on it. Also, I used polygonal lasso in Photoshop to do much of the work. Maybe that was a no-no, I'm not sure. I'll happily spend some time tweaking it and re-uploading, or will start over if necessary -- any suggestions are welcome. Many thanks.
