Hi, I am not the best in this forum but I like to render with Corona 
I would like to know how I could make the last renderings in here better, any tricks to make this looks like real-life-photo?
I would try adding some structure to most materials, some subtle bump map. I also think the colours of elements don’t look very realistic, they are too much saturated. Lighting has huge impact on realism, you can try playing with it.
