In this shot, the verticals on left-hand side and right-hand side are all leaning to center, but with different angles. Please make sure the verticals on LHS and RHS are roughly leaning at the same angle in your original shot.
Actually the middle verticals in this shot are slightly leaning to left. All those indicate some clockwise rotation needed.
