Hmm, I have an idea, well first finish the clouds (duh!) and then maybe like a funny little elf in between the hedges would look nice because of your expertism (if thats a word!) in lighting would look nice on the elf's rosy cheeks!
Very good picture!

Hmmmm... I really like the background. Reminds me of a Super Mario game for some reason. But more enhanced. Or it also reminds me of a really nice day outside. Cool drawing. :D
