ECA race circuit I just thought of... what does anyone think?

I tried to come up a somewhat realistic street circuit on ECA and this is the result so far. I'm inclined to believe there is potential there, but there are also some problems:

-4.9 miles a lap (which I suppose isn't that much of a problem, but still)
-Narrow
-Very rough bridges (though it could just be my using the LMSC mod with default setup)
-Where to put the pits and paddock?

Comments? Suggestions?

(After more testing, some of the braking zones genuinely are genuinely awkward and so the layout probably does need to be adjusted a little bit.)

 

Pits: Purple
Paddock: green


Just as a suggestion

 

I mean, it looks a bit long. The long sweeping corners might be nice to drive but in my opinion are more reminiscent of a hillclimb course than a street circuit.
