Woke up and back painted

Yeah so I got up at 7:30 ish and did the back painting for my new painting. Or some of it. I've got a general idea but the back areas don't seem to make much sense which isn't normally the case. Normally they make the image form and pop out. This one is a bit different anyhow, but it makes a significant difference to the image as a whole to get see the back in place because I can normally tell which bits are working in regard to the composition. Not convinced they do at the moment. But no point giving up. It's like looking at cake ingredients and deciding the cake will taste crappy.
