Light source and environment picture are in contradiction as like in direction as in color of light. RK

This is a good start... the modeling looks good, but I think your materials need some work. the sky image doesn't match the mr sun and sky... your scene lights say "middle of the day" while your background shows either a sunset or sunrise... your stone material needs more bump or some displacement (same with roof) I would either photoshop some grass into the scene where needed or make use of proxies. The image seems cropped a little tight, it might be nice to give it some more breathing room on either side. The placement of the two goose neck lamps makes no sense to me... maybe get rid of those and provide some lighting around the pool for late night dips!
