try adding some displacements with the grass and add some textures to the wall...

Nice work, the image looks good...its just the sky that looks a bit uncool. Try dipping into some more skies, just in case u need to change the overall light color too..do it! it'll look more appealing..:)

OK, Juraj! There is no limit to perfection :)

You payed a great attention to putting lights around the whole scene, which is very good ;- ). If I can suggest, I would put few also in the swimming pool under water (and make the water slighly more reflective, maybe also adjust the IOR a bit). One more idea would be to re-work the metallic material on top of the building (If I understand it correctly though) for higher reflection (maybe the fresnel is lowering it too much for you, it isn't necessery for metals). Just my input ;- ) Otherwise good job !

Thanks! :)

nice rendering. I liked the swimming pool specially. nice concrete work in the second image.
