Speaking only about the rocks, they could use some work again. I know you added more with a bigger variety in rocks, but I think you need to add color to them. I personally collect crystals, so I can tell you they are all different colors. I'd recommend using purples and pinks and blues and green, not just more stone and gray. Also, I'd personally like to see a little bowl with some smaller stones in it because the rock tumbler is there to make the rocks tumbled and smooth. As always, I love the parkour, but I think it would be cool to see some other rocks there :DD
