I need some suggestions on how to make the picture more real
@q844532495 , so right of the bat I can see that most of the textures have visible seems to them. In this case it’s better to use textures which give the building a more uniform look overall, here is an example. Feel free to generally inspire yourself with other showcase renderings of course. 
Furthermore, I recommend to also use a bit of a higher resolution skybox in your project, or simply select one of our horizon presets via the Atmosphere tab. In your case, the background does look pretty blurred, which takes some quality off of the overall renderings. Among other websites, https://hdrihaven.com/ for example offers high quality free to use HDRI files!
Alongside that, just play around with the time of day as well, additionally feel free to make use of the following commands to finetune your sunlocation even further:
| SHIFT + U / I | Change the solar angle |
|---|---|
| CTRL + U / I | Change the solar rotation |
Finally, and that is a matter of preference but, maybe you want to add a few more trees and vegetation to the grass area to make it look less empty, same goes for maybe adding a few people here and there, or other props from our Asset Library.
It’s also a matter of playing around with perspectives, getting inspired by other creations as mentioned, and with time you soon get a better feel for creating realistic renderings in general! By the way, your current renderings still do not look bad or anything.

Good suggestions Thank you I will try to modify!
