Old Black Tree

Recently, I was up at my father-in-law's house.  His backyard is full of of trees and bushes that surround his pool, but there is a wonderfully twisted, old, black-barked, tree that rises behind the pool and captures my attention every time I am there.  I drew it a couple of years ago during a previous visit, as can be seen here.
While relaxing in the backyard during this trip, I had to pull out the sketchbook, once again, and scratch out what I could.  It started to get dark, so I wasn't able to capture much, just the bark on the tree and a few limbs.

Once I got home, I wanted to continue to play with it, and embellish it a bit more...so I continued to add the fence, a neighboring pine and a couple other embellishments...

All in pen and ink.
