I think the layout should hug more with it self. You MCBR could aim more at the lift/drop so the return back was more together. Otherwise it looks pretty good, drop shaping seems fine to me, maybe a little strong on the G increase?
Thanks, TheArchitect! The layout is going to have a lot of terrain interaction, so I didn't see the need for the layout to hug itself that much, though I have considered it. And are you talking about the pull up or the drop itself?
EDIT:
Here's a pretty good picture of the drop/layout/terraforming/whatever.
