Ok, but my question was: did you correct for a possible the difference
in angle between the two renderings?

The only one that does not look flat is the 3D model. I have trouble
telling why, perhaps it is the lighting. It can't be the whole story
however as I can not tell if she is standing in the shade (when the
lighting might be correct) or not totally as the 3D model seems to show
(though that could be because she is not exactly in the same spot).
Then there is also the problem with how the feet touch the street. I
noticed that already with e.g. the man in jeans on the left. It might be
that they are rendered standing much closer to the camera than the
billboard does in the final scene.
I am a bit confused.
BTW did I tell you I like the scene regardless of these minor things?
