Imagine this is not a tree but the massed tentacles of some eldritch being, writhing in motion to a long. slow cosmic drumbeat. Devotees of gothic horror writer H P Lovecraft will recognise the allusion and also the Lovecraftian reference in the title of this piece.
I absolutely love the starkness and the snow dusting the branches is perfect. I can see the implied movement. Trees in winter have a great deal of character.
