Old Gnarled Tree

I thought I would use the rest of the strong coffee and do another BYOB Zentangle.  I painted the tree with extremely strong coffee.  The mixture of the coffee with the light blue mat board makes it look browner than I ever figured it would be.  I decided to use Nebula for the sky since it looks like it might be night.  I don't know what I used for the tree since, as I have said, I am new to Zentangle and don't know the names of the tangles.  This is 6 1/2 inches by 4 inches approximately and is also on a chip of mat board.
