Thank you for taking time in replying, and your advice.
I Totally agree, and why i had my ref updated the beginning of this year, so it won't happen again. Though ill have to update the part about Paypal, too. Its true some clients were put off by the idea of using Western Union, but I didn't had a choice in these parts of the world where i live. So I'm just glad I've finally got a working Paypal now.
The image in the email was a low res - quality cam shot to provide proof, and never received the full image. but even that didn't spark or inspire the urge to pay to get the full better quality ress. I only posted the image 6 or so months later on DA having a feeling the client may never return anyways. Now its just for profile promotional use. And thanks, I'll use your advice on titled "Unpaid" watermarks in the future. 🙂
