the only "bad" thing is that the ground is too flat outside the hous eon cell 1.. with some magnets and a better grass/groudn texture, you could have made some little slopes or something... or had postowrked the whole cell with some sepia + aquarel effet for a nice look.. may you try (but gee if you are on a celeron with 128 it is not courage, it is rage ! good luck)
