If I read your diagrams correctly, your track goes in to the closet one door and out the other door, with both doors being fully blocked. How will you get in there if something derails?
If you choose to use the closet that way, I would put nothing but broad curves in there while fitting the crossover between mainlines on the exact opposite (and open) area of the layout. I also agree with GVDOBLER above, trains only capable of running the same direction, without the hand of God, can soon become very boring.
