The quality of that render reminds me of an architecture student thesis project, not bad but not great either. There is a Argentinian arch viz studio that uses blender and their portfolio is impressive, better than any YouTube tutorial I've seen. I recommend you take a deep dive into their Instagram since occasionally they will answer questions about their settings in the comments. Their handle is: bs_arq

As another anon has said in here, study the composition of architectural photography, go on archdaily, dezeen or divisare to look at different architecture projects from around the world. You will find the photographs follow basic photography rules. You can use the best pbr materials and use the best looking trees in your model but if the composition sucks then all your hard work will mean nothing. It will make or break your project if you are an aspiring architect or archviz artist.

Start training your eye in architecture photography and the rest will come easy, as long as the buildings you're modeling aren't shit looking. And look into matte painting, you'll get better looking results than trying to do everything in 3d space.
