Excellent track.
Reason for four-star: I frequently visit this track, you need to include the white tower that is visible as you come into the St. Mary's left turn.
It's used as an indicator by many drivers and is a key reference point on the track.
It's the only part that stands out - I get to the corner and I'm thinking "where's the tower!", almost as a panick because I don't know when to brake - haha!
Otherwise amazing.
(just fix a couple of tarmac edges that make the car fall off the world and tumble into the abyss).
