Not a problem ^^'

I noticed you said you tend to go more for nature landscapes than cities.

With buildings and such, it helps if you mark out your vanishing point(s depending on what you are going for) first to keep everything in line. Right now you have a vanishing point cluster for each individual structure, which isn't how the human eye sees things. You have to have a vanishing point for the whole urban landscape first, get the basic buildings in to fit that line of sight, and then go back in for the details with the same method.
