If we're going full nitpicking, I can list some particular stuff:
1. Some of the roads to the houses around the start/finish area looks like legit routes. I think 0:19 and 0:25 are good examples. I'd either put some vehicle on those roads to prevent players from driving there or use some red cones to mark the map boundaries. Not crucial, but still something I'd do.
2. 0:34, 0:42, 0:55, 1:09, 1:32 - Consider using a bit more props to make it slightly more noticeable that people shouldn't drive there. You can use
this website to browse different SA props with ease, instead of using the editor search.
P.S. Could be just me but the reverse looks way more fun. Probably cause it's more speedy and less climbing. Overall, a lovely map, should be added.
I swear, literally any map in this area looks better than Calton Heights. I truly regret working on it now, lol.
