Can you explain all the little bounding boxes for the grass? What is that method? I think that goal of mimicking the archviz look was really well done, glare and all. The way you work in the haze and atmo perspective is excellent too. Great work and very uncommon!
excellent job! this is amazing
Rendered in Cycles.
The girls was placed in Blender, just planes, scale checked. The seat is far long from common sizes (keep by original concept), maybe this give the visual sensation that is out of scale.
I agree that there’s a lot of mistakes. After a work done I need some time to clear my mind and then analyse better. The framing of second image and some composing are things I think that need to be improved. Thank all criticises, I’ll try harder next time 
This is just a method for better performance in viewport 
The grass is instances by particles. You can see the geometry in this image:
great job. can you share the setup of the glass and light please?
A delightful work of art. It isn’t just an attempt to demonstrate to the viewer that it is a photo of reality, it is a work of art.
I like this picture, it is really good. The compositing is really cool.
