0:08 Glen park looks quite messy, be consistent with the objects or put invisible walls instead. Only arrows for the first intersection and inner part of the track afterwards should be enough.
0:18 Add arrows. Having this corner's arrows connected with more arrows on 0:15 would be nice so we know how much we can cut here.
0:25 For the sake of potatoes out there please remove the train.
0:31 put better/more fitting looking barrier or put arrows instead.
0:41 The arrows ate up the outer sidewalks. Stretch them more.
0:45 Arrows pls.
0:55, 1:05 Yet more improper arrows placement that eats up track width.
Route is nice, name is generic. Few arrows placements should have some rework. Seems like decent map overall, would love to see some improvements.
