The layout felt alright, you placed the checkpoints correctly, and you're using barriers and apex props in more or less the correct fashion, but the last sector of the map with all the harshly cambered corners could do with some changing. The first half of the lap is more enjoyable, IMO.
Maybe check out some of the tracks in Broughy's content creator streams for some better ideas on how to utilize the larger stunt pieces in relation to elevation change.
Also keep in mind that I am biased toward Event style tracks, and strive for semi-realism in elevation change and corner cambers. If you were intentionally going for more of a wacky, fun, playlist style track, then more power to you.
