Tree Drawing, perhaps surreal and/or psychedelic

Here is my newest drawing of a tree that I call, "Inner Glow."
I suppose it is apparent as to why I have chosen this title for it. This piece measures 8 x 8 inches and I created it on 140 lb., acid-free paper, using a variety of pens on paper.

It is also for sale on Ebay.
