Cabbage painting

I was fairly pleased with this but I lost sight of the overall pattern of shadow. I also didn’t get the difference in colour between the front of the leaf, seen in the background, and the back of the leaf, in the foregeound. The front of the leaf is much bluer and the back more yellow. Perhaps it was a little overworked, but I don’t know what else I could have done with a subject like this.
