I like the different types of clouds at verious layers of the atmosphere. Always a photo when the crepuscular rays flow. Birds are almost always a distraction. A bird fly through almost always wrecks the shot. Your birds are hardly noticable. I do think you've chosen a very difficult angle to the sun. That said, I truly enjoyed viewing the elements of interest n this scene.
i like the leading line of the larger concrete blcoks and the way the light rays stand out, the mix of different clouds is funny and catches the eye. there appears to be something jus to the right of the tower half way up
