I don't think anything sucks here..! As for the buildings, I could see right away what it is. Only two things caught my eye as not quite right: The fallen trees in the background seems to have fallen in odd angles that doen't look natural to me. Maybe you could make the gate look a bit "deeper" - it looks more of a mirror-type thing to me than a gate that you're supposed to enter. But still, adding people could change that impression a lot. I think it's a great image, please do post the next WIP!
