Yes, exactly what I meant. Although you put it in better words. I think basically you're doing great stock for people like me, that once in a while want to study a reference for linework / painting, while many people look for stock that is just pure, well, stock material, ready to use as a whole in photomanipulations. I find both kinds of stock useful as reference, but I prefer your kind (clean photos, no strong light) when I need a good anatomy / pose reference. Yours is perfect for that because of the quality (even though I never directly copy any stock).
And I agree that *Ribeyedsmile is a good critique, just wanted to add my two cents that it can be great material for other people and different purposes
(Sorry for babbling so much, I'm always afraid that when I add my point of view just for the fun of discussion, some people will think I try to argue, when I'm not. It's just fun to talk once in a while).
I like your comment and respect your opinion, I just wanted to write why I disagree on it being only fair as a tool of reference. In my opinion this is one of the most useful series I've seen for 2D animators and such, myself included (I'm just going to have to do a traditional animation of a person lifting up a head, actually, so I know I'll be looking up at this piece a lot).
The fact that the light is neutral is what actually makes it even more useful - it helps to see how the proportions and "lines" change. Very useful in drawing linework. I think a face / angle reference with varied, strong light would be just as useful, but it should be a different piece. This one is great and very useful just as it is. At least for me. I love it!
