1. Such squared arrow walls (0:03, 0:21, 0:29) was often considered a bad design decision in the past (0:21, for example, doesn't tell the player where they should turn on the reverse route). You could possibly use the "Green Sabre" map as a reference point, to see how it was done by us with Evov. Because the start area is the same, though it was decorated in a different way.
2. Some of the arrows on this map are placed way too deep and the players wouldn't be able to see it up until they reach a certain point/turn - 0:43, 0:46 and 0:49~0:52 goes as example. The map isn't a huge one, so you could possibly invest some time into making it to look a bit better.
3. Opinions and all, but the name of the map is too generic.
