This is definitely a cityscape, not a landscape. Those buildings on the right have a serious lean to them which detracts from the composition a bit and makes it look a slightly odd. It can be fixed with lens correction software such as "Lensfix" 10
I'm not sure there is a tree or even a speck of soil in this scene. (OK, I finally spotted a limb off to the far right edge). I know such a scene can sometimes fit into the definition of landscape, however it's just not fitting what I consider to be a landscape. Sorry.
