I think the idea was really cool. Lots of space to explore and really have some fun.
However, I don't think it was executed properly. Not a huge fan of the gradients of the supercross track, and the other tracks were a bit overscaled.
onto the woods track, I think the trees are a bit overstressed. Less is more.
I'm really enjoying this track, however I think some things could be better for your next track
thanks for the track, it's pretty good for your first one!
