Here is my Corona vs Vray test Scene
Criticism and comment For Make My Render More Good.
Thanks.
Firstly attention to details.
Some things that bother me when looking at this scene:
TV is a black plane : where is the reflection, how is it attached to the wall? No wall mount?
The cabinet beneath the TV again has no reflection. Add a vase or a book or something, vase : Spline → Lathe, Spline loft → Bend Twist.
The chair is just plane ugly, unless you have an Indonesian style looking garden or something I wouldn’t use it.
The carpet… If you aren’t used to work with fur material try a simple carpet texture with a cellular map in the displacement slot, ad a mix map, a fallof map in the reflection slot.
The couch: I can see the edges running on the spot where you rest your arm. To make a cloth material add a fallof map in you diffuse slot. Play around with the curve tool.
The plant in the back is to green, almost fluorescent. Tone it down, Add a texture to the leaves.
The floor could use some extra details aswell. Bump mix map : Scratches or something.
Your lamps are not lamps, they are just white dots. it’s a daylight setting so use regular glass, or something.
And some additional idea’s
- Add some photograph’s on the wall.
-Reduce the bump of your wall.
And most importantly :
Corona is like making a soufflé, you don’t want to take it out the oven to early or it will fail.
Oké all done 
Hope this helps.
thank you for wonderful reply. your reply will make my work perfect
Your welcome, show the updates.
How have you set up your lights? The image looks flat, the illumination is not interesting. I would try to play with the light settings: intensity, direction, etc.
