Very nice! I like the glass shading!

well really nice ... and i hope yo don't mind some critic

while thi horisontal lines go to a single point, and object farther away are smaller, you did mess up the vertical lines
look at the left building, the groups of three windows ... the ones closes to us are the same width as the ones farther away ... but those that are farther away are lower, so they should also be narrower .. (if the vertical line is half smaller, than the horizontal line should be as well)

but keep it up .. that's always a good practice

wow man excelent design =D
