Don't want to rain on your parade JMR, and most certainly appreciate what you are doing, but your watermarks are well, a bit over the top.
I'm a bit of a graphic design nerd myself, and taught my class graphic communication & graphic design ( mainly because my teacher was a fat slob who was so far up his rectum it was unbelievable ) , but unless you are doing exceptionally high quality paid work, you shouldn't be putting watermarks in. Even if you do, make it small and only a symbol. Overall though, it would be better just to ask for you to be credited in their work, rather than have an incredibly obvious watermark on the top.
This is going to sound incredibly obnoxious from me, but I wouldn't put watermarks on at all until you get to a level that it's necessary to have watermarks at. It's obvious that you are using photoshop, but it looks like you are a beginner. I'd wait until you get into some pretty heavy stuff before you start opening yourself up for requests.
Apart from JMR, you guys should be being more specific with your graphic design requests. Just saying "I want XYX and the colours to be red" is not useful to anyone. Giving a vague idea of what it should look like ( Even a vague idea is infinitely useful ) will help a tonne, and will make your logo look slightly like what you want.
