I always like the way you get a nice composition together, and you get these very bright scenes. I like this as well, it has a very pleasant atmosphere (especially if I look out my window now.. dull and gray).
I do have a few comments (as you want to improve); why not dump the front trees? I think it's stronger without them. Or replace them with a very bleached dead trunk or branch (not too obtrusive). And the two sets of shrub above eachother right behind that could be slightly different placed, IMHO.
You might want to try the Mitchel Netravali filter, and go for soft shadows!
