And the raised level of Janeway's room makes it look larger with those huge windows.
EDIT: Two fairly accurate meshes for Poser of the Janeway and Picard ready rooms, which appear to have been based on stage drawings. Textures are not Trek authentic. Janeway's room is on the left, and I've removed the big window wall. The light colored speck in both rooms is a human female figure for scale.
Dude I dunno where you got these but while the porportions look close, the scale cant possibly be accurate.. Picards room looks way bigger than it is on the show. I also note the lack of the couch he kept behind the chairs.
