the only thing i can see is that you are not taking advantage of your longest straight. if you had something along these lines (give or take a few straights pieces)
you could really get some speed thought the left corner if it was slightly banked and then fill in the rest of the table with twists,hairpins etc. unless you really wanted a bridge. but in digital you don't need a bridge because there is never a bad lane to be in.
