You must have a really bad experience. I visited your gallery. It's "Closed". Okay...
So, I share what I think - this is my opinion. If there are "design and interfaces" cathegory, and I'm a graphic designer, why I can't share my work to show? This is an online gallery. I don't do design thing just for art. This is my job. I doing this thing for payment. This is normal. I don't understand you now... And I share it because I'm interest the opinion of other people. Like Mendicant, he suggested me a very profitable observation on this design.
Or you think that what I've done for payment is not art or not for show for a lot of people? I can't be proud of them and share it?
My request is normal too, I think. And as I wrote, I asked permission from those people who payed me for them.
Or you think it's not protected? Please tell me a method how coud you (or anybody) "steal" this design for example? It's low resolution with watermark. Maybe copying, but I tell you something. In this profession almost everybody copying the others. This is a fact. Just look around here. There are a very few really original design or artist. And the originality of the corporate design depends on the clients reqests too. I think clients are designkillers. All of designers knows it. I think this is more confusing.
Maybe you take this all s***t too serious.
Anyway, I think it begins to down on me what do you wanted to say. But not really...
Maybe my poor english (sorry for that) prevents it.
