5 levels of complication

 I have been doing some more work on repeating patterns and tonal tiles. This tile has 5 levels of tone and can be put together to make pretty interesting patterns.

Here I took a tiny photo of guitarist Keith Richards and reworked in into a big tonal portrait. It would be great to make this as a giant wall mural using octagonal tiles. I am making a few more portraits to get the procedure more streamlined.
