- Nice idea so far. I loved the camera during the parkour part with the shader, everything fit together and loved how you changed grass color to give deep impression.

- Try to take moving grass, like a movie part or just a gif. I think the main quality about having something natural in a video is the natural moves.

- The shadows are purple on green grass ? ^^ I can send you a "totally green" shader for greenscreens if you want.

- During the parkour I have the impression that the parkour stuffs are flying over the grass.

- The part with butterflys is a great idea but need more works on fitting Toribash's camera and texture movement.

- The sounds managing is a bit better than your previous video but still too loud I guess. I think sounds doesn't have to be louder than the music itself. If the tori is close or far from the camera it should change the decibels of the sounds too.

I think the music fit very well with the video.
Keep up your good work
