Even tho all those ideas have been used already it is good to see someone is going to rework on them.

I specially like the cliftside parkour, it is quite good. You should use the first 16 objects to make more interesting things such as a breakeble floor or maybe wearpons to fight in the spar. Those trunks you added dont look too good, and those rocks should be a bit bigger in my opinion.

You nailed it with the ambientation, I would move a bit those trees since most of them are in the left.

Instead of making the fence broken you could do it breakable, which would be much funnier for those who spar in this mod.

I hope this helps you to make the mod better

pd: add the wip so we can test it, I could only watch the screenshots.
