I realise that this is still a work in process, so ignore the comments if they are not relevant. I love the use of the apples in the background creating almost a theatrical back drop to the subjects in the foreground. The part that I feel you should consider when moving forward is the style of the figure and the style of the horse are not the same and because they are on the same plane withing the painting it becomes a little awkward. The idea and playfulness of the work is wonderful. Look forward to seeing the completed work.
The horse isn't done, it is pretty much like the rest of the picture 2 levels deep. I figured out the style with the tree and I will integrate that throughout the painting....right now nothing jives, that's usually what happens when I am still in the second layer...just wait, I got it!
I have no doubt that it's going to be incredible when you've finished, you're more than accomplished enough. Good luck.
