I think that the mast may be plumb. In some of your photos, it really looks badly misaligned, but I also look at the buildings and the fence and other objects in the same picture and they seem to be off in that way, too. The mast looks horribly misaligned at first glance, but I think it is more an optical illusion with the camera angle. That you can check and correct easily.
The major problems are that your LOS is blocked really bad and you do have the dish elevation and possibly even the motor latitude angles set incorrectly. I don't think you are far enough south towards the equator to warrant that steep of an angle. When you factor in the offset angle of the dish setup with your dish elevation setting and possibly the latitude angle of the motor, you are nearly looking STRAIGHT UP in the sky!
