According to her site, she uses water colors, pastels, and pencil.

And to answer your last question....if she's asking for my permission to use (not necessarily Flickr pix) my pix....I would say I do have an entitlement.

But then again HD....that's my question, other than saying no to her using my pix, what do I charge and how do I maintain my rights to my pix?

Thanks
Bill
