Pool scene

This image has potential but you need to work on the textures and lighting to pull it off. The stone textures lack depth and the UV mapping on the stone posts is off. I'd also change the background, not sure if you were trying to hide something on the image but that white glare across the sky makes no sense and really wrecks the tone of the night image you were trying to create. The modeling is good and I love the pool water and pool.
