Darn! I keep hitting some key that deletes my post! Parkinsons!

Not everyone has the the time to model all the things they need in a render, that is why there are so darned many dial up characters in the the market place made with Vendor Resource textures... a lot of Poser products are about time saving as much as sharing a little bit of the vendor's vision.

I think your design and conception are very nice. Your creating non-copyright-infringing textures is also valued added. I think there are those textures that need further work but the way the paper is really dimensional and has subtle folds or relates to the mesh beneath it  is very nice and sets this apart from a simple assemblage of textured primitives. Maybe a full desk clutter set would be  worth $5 or even $8 to people doing commercial work at least. Certainly for my own personal work I want all the mess I can affordably pull together.

With all this kind of thing I say do it without any expectation of financial return, just make something you are proud of... just make sure it is the best it can you can make it. Be dedicated. If money follows that is a nice bonus. Maybe you will have helped out a couple people in making an image they want to make.

My only problem with weak things going to market is if they are dishonest in their promotion, someone not trying their best and then trying to hide the weaknesses or shoddiness to make a sale, but so long as the promotion is really "what you see is what you get" then no one gets hurt. They don't want it? They won't buy it.
