yeah i think so!
its tough because of the retro perspective. make the shadows too realistic when the perspective is not could lead to pains in the arse area
^ image number 1 is how id probably do it, keep it simple and have the shadows ignore the perceived upwards tapering of certain walls.
image number 2 was my attempt at getting the angles of the shadows more realistic on the sloped walls but im not a fan
in both images i made the shadow cast by the door narrower, moved the triangular shadow on the other side of the door in a bit so it was flush with the corner, and knocked a pixel off horizontal shadows for a little illusion of perspective
