Prefabricated VILLA

I use HDRI image for skylight & Background and i Intuition the grey cloud 4this :(( I used vray ambient with radios 0.5m for this scence, is that bad or good ? And steel structure : this is a base for growing foliage on it about green colorization i have no idea MAN :(

Good one but why the clouds at the corners are so gray??? any particular reason??? and wat is that steel structure at left end of the image???

clouds are grey because of vignetting right? model and materials look great, but there's something unreal about the overall colorization, and maybe the vegetation is too saturated in the greens, and have you tried adding ambient occlusion?
