As Rofflestomp and Floon have stated, a big push on the environment polish is underway for September. Glad someone noticed the grass. Adding personality and polishing assets that we feel didn't quite hit the mark is definitely in our cross hairs for this next update.
In regards to cloth physics, a polish pass has also been happening on characters that could've used more love. Cloth I'll say is extremely challenging, especially with the responsive nature of the game and yet, look and react well at all times, as I like to say, we're harnessing chaos. You want the cloth to do whatever it wants, within known constraints and when you have a character with some extreme animations, it's challenging.
