Couple things:
Traffic! Everyone used to yell at me for not having traffic, well, you need some!
The clouds look like a checkerboard, you need some other types in there to break up the pattern
The angle is a little weird, the horizon isn't level and that makes it strange too look at
And finally, the sun. You either need more or less of it. The little sliver is too little for me, it need to show more or none at all.
Just some constructive criticism, its a nice shot but could be better
