Welcome to the Forum. We were pretty much neighbors. I’ve been in West Mansfield for about 30 years.
I like your layout plan. Looks like you can run a train on the outer portion and be able to operate some switching moves on the inner portion. You also can reverse direction. The only thing I can offer. Where you placed the double x over in the center. There’s a short run around track. I maybe would incorporate some Ross curved turnouts and extend the length of the runaround.
Nice plan. Not a lot of complicated trackwork with room for scenery and structures.
