Hi all, this is my recent project with enscape
Hope you will like it !
@VuTienPhat , welcome to our Forum, and thanks for sharing your renderings with us. 
I like them already, and these may still be work in progress, but to improve the scene further I highly recommend adding either one of our horizons through the Atmosphere tab in the Visual Settings inside of Enscape, or importing your own Skybox as a background:

You should also be able to find a good match for this scene more specifically here:

In this case, both the backgrounds “Helipad afternoon” and “Helipad GoldenHour” could be a great fit for your project especially. Just as examples, you may want to use a different one entirely.
Thank you, Demian?
thank you NoMasCorona
Very realistic. I was going to say before, but deleted the message, that you seem to have subtracted color from the renderings (almost black and white), and I really like that. I could learn from that. Or maybe you just used very neutral colors.
Thank you so muchh, NoMasCorona
Just to confirm, when I use an HDRI I can’t adjust it’s height, right? I have to move my model up into the sky if I want it to appear to be many floors up? I always forget to do that and now I have scenes already established in my SketchUp model, on ground level, that I would not be able to use anymore. Thanks.
Actually when I try this Helipad HDRI you mentioned I realize the vantage point is already up in the air. I would like to find more like this.
