Hey so for the prison, I have a suggestion, an interrogation room. Like the ones you see on tv table 2 chairs, 1 way mirror, cameras etc on the other side. These are old images from a way long time ago, but I checked and they still work the same, its a white board, for the 1 way mirror, could be used as force fields too i guess. One side is white board the other side is invisible. Your looks great! I cant wait till I put some time into one myself.
