Agreed with the above comments.
3 would have been better, IMO, if you caught more of the stairs with the signage tucked into the corner. To give an idea of what I mean, one of mine (although with mine, I'd have preferred even closer to the wall, just there was downed electrical wires that made that a non-option):
For 5, if you had done it from the corner of the roof visible, with the top of the clock tower at the top of the frame, you would have got a more visually interesting image, IMO.
