Very cool!
The plants look very realistic, as well as the lighting.
The blue texture on the sculpture seems a bit blurry ( I don't mean the DOF )... the only thing that reduces realism in this image.
Hi, thanks for your comment!
The blue material is made with a mix of procedural textures to replicate the bump imperfections of the ceramic paint. It may looks strange because of the changes in reflection, but is not a blurred texture :)
Also the gold paint is made with a procedural approach, using a Corona AO that recognize the displaced surface and another procedural noise into the AO distance.
