What I like about this valuable group of leaf elements, Arnaud,
Is that they are photographs of carefully lit sculptures. As such they give us an opportunity to see real light fall upon the elements, creating shadows, they are therefore very good sketch subjects, where we can learn how to draw our own shade lines.
Martin, yes I know by now that Gargoyle posted it in the cafe a while ago. If I would have remembered, I would not have posted it again. But anyway, it seems some other members didn't see the pictures until now.
I'm sorry I couldn't remember where I got them from, probably because I have a small head and too much information to store.
