I love your brushes as well! First, thanks for offering them up as a freebie; I can't say that enough.
Second-I have a question. I am making a texture set to sell for a poser model for 3D rendering, and would love to use your brushes for making the tats on the figure. The tats would be flattened on the mapping onto the skin tones, and I would love to credit your work as right if I may use them in this manner.
Please let me know if this is acceptable to you? Thanks again!
