NEW TRACK PLAN FOR MY PEAVINE SUB

hello to all
i am currently in the process of buying a home. while i am waiting for all the papers to be signed, inspection & appraisal to be done, i have occupied myself by drawing up a new track plan for my BNSF Peavine sub. this layout will occupy 2 rooms 1 bedroom & the den that is adjacent to the bedroom.the bedroom measures 11ft.x 11ft & the dens common wall ( with the bedroom) measures 11ft x 9.5 ft w & the final measurement is the left wall of the den @ 13 ft. i intend to go through the wall that separates the 2 rooms giving me a run of approximately 19 ft.on the lower level & the same with the upper level.
i am attaching the drawings of my new track plan to get some comments & suggestions. i am using ME code 55 flex track & a combo of Atlas & ME turnouts. the scale of the drawing is 1 inch = 1 Ft. & is not 100% accurate. i will be using a helix kit that i will be purchasing from an ebay vender. the helix is built for double main line with an out side radius of 16.5" & inside radius of 15" @ a 2% grade. spacing between levels = 2". measurement of the kit = 36" by 15".
so here are the pics...let me know what you all think

thanks ...vinny
