This is the shadow of my hand, I think it is trying to catch the falling feather. I have also worked on some of the other shadows in the painting. I think I will need to work on the overall painting once I have finished adding elements on Saturday. Thee are just a few bits that need a little bit of homogenising. Two more objects to go and I know what one of them is!
I just noticed that I also added a hand coming in from the pictures edge yesterday, sometimes it's like my subconscious mind is making decisions for me... Brilliant!
