It's really good, I liked this work.
I just choose another starry sky to be more natural because this is not very convincing, IMO ..

I changed the stars DanielaOwergoor, to make it look more realistic. Thanks for the advice.

Very realistic and very good idea!!
Good job author!!

I agree with Daniela, the stars look giant, from a roof you cannot see such big dots on the sky. Anyway it's a very good change, good work author.

Lighting seems unpersuasive to me a little. Nice chop otherwise. Good luck author.

Nice scene, proportions are believable. I do think however , the foreground should be darker and the contrast on the rooftop should be reduced. Apart from that its a nice job.
