Sorry - this was my fault for bringing up the watermark issue. I've taken away from what are, at the end of the day, some pretty cool pictures, which is the point of your post. I'd be proud of them. You are sharing your work with us, and this forum is a better place for it.
You can't ignore the watermark issue, though. I do agree with you, and also with Schruminator about the necessity for some kind of copyright protection - it becomes even more of an issue when the material is of the quality of yours - after all, no-one wants to download a poor photograph. I'm not well versed in the practicalities of inserting non-erasable info into file data and I'm sure you'll settle on something that works for you. I would point out, though, that all you really have to do is rest happy in the knowledge that no-one can do anything worthwhile with the typically small files that appear here.
My thinking on your pics is simply that the copyright symbol is so excessively large and intrusive that it really detracts from the appeal of the photo. It's not even a creative reflection of your work - it's a '(C)'. I can't look at any of your pictures without having my attention pulled away from the point of them - the symbol becomes an intrinsic part of the composition and as such, because it's compositionally unsympathetic, it ruins it. It's no longer 'art'. You need to understand that anyone even remotely competent in CS6 can get rid of anything they want, so you're not really achieving anything by doing this.
So again, sorry for sidetracking things, but your photographs have brought up an important issue that should concern us all.
Keep up the good work! I like it.
