Slick render, Bobby. I do have some ideas, if you want. First of all; much more dirt, on the house, ground (grass can have some of them leaves or branches or rubble). The front drive I would make some sort of tarmac (tiny fake stones, and some mixed 'blacks'. The large tree doesn't have a very nice bark texture. It's too big I suppose. You could grow some ivy to hide or use another texture or tree. And some pops of trees on them far hills?
