I agree, in fact it almost appears as if the cam on the lift would actually be too high. The cam on the pole would be too low imo. Can't quite get the angle on SV. Shame about the buses on SV, they obscure the Northumberland Ave sign which we could align with the "off" lampost to get a reasonable approximation of where it was taken.
Also there is the LisaMI6 pic, which cam was that taken from? Possibly these pics were taken by people on the ground, from the bridge. The perspective of the top of the Bazelgette memorial does not look far off at all. I need to upgrade from paint to something that will do transparency.
