It's really starting to bug me, what kind of tree this is. If I remember rightly it's technically a shrub which was planted by the previous owners, and grew tall as there's little light at ground level.
This is an oil board, about A4, which I covered with a thin layer black and red acrylic. When it was dry I squeezed out a load of white acrylic, and smeared it around with a plastic palette knife, then started scraping back to the black to describe the trunk and branches. After a while I added some green, and then some red as a contrast, and mixed all three to make a pale grey/lilac to suggest the floor and the wooden planter.
I hate it as a painting, but I loved it as an exercise. I should really do some more of these to see where they lead.
