Ummm..The light would not come in like that from all sides(well...assuming there is not some type of candle or other light source sitting right outside of each window!!!)

Also, your tree shows don't line up all together. The one on the mid right has the light coming from almost due north(or up as the case may be on this map) while the ones on the right have a NW light source. Then the plants outside on the back wall have lighting from SE and the gazeebo/arbor and well has light from due West.

It's a good start, but I think, nay I KNOW you can do better....(just a challenge....heh)
