Guys, thanks for the comments!
Yes, this time I used only Hdri, no additional CoronaSun. And I think that was old&good 1230 or something around sunny hdri. For night, I think it was one of the oldest dusk hdris :)
I have to admit that people are bit off after sometime I see it again. But anyway, thats a nice couple and client is happy about that :)
Thanks a lot again!
