Desert Tree Redux

I'm cheating just a little bit here - this is not a new piece of art.  I originally drew this way back in 2005.  But today I revisited the digital composite file I have for it and made some improvements - adjusted the levels to boost the contrast, cleaned up a lot of the scan artifacts and errant pencil smudges, and went back over some of the linework.  I did all this because I wanted a version of this image that would be suitable for prints to be made of it, and then I made a version that (hopefully) works on apparel as well.

To that end, this is now available on:
