That is quite a lot of progress!
Somehow the bubbly miner doesn’t seem scary, theatening, or gross to me. Maybe it is the eyes being too clean, or he isn’t goopy enough. He reminds me a lot of pizza the hut from spaceballs.
If you wish to shock the viewer more you should think coming in closer with the camera and/or having a stronger reveal…maybe it quickly moves under a downward spotlight, the camera pushes in really fast and goos spills out of his mouth. Right now the flashlight shining on him seems very casual, as if the owner is simply searching for a lost puppy in the dark. The bubbly miner even breaks eye contact with the camera. Better might be that the miner isn’t making eye contact, or even facing the light, then it suddenly snaps to looks at the camera (I am sure there is something like that in the Thiller music video). Then if he did something more threatening like move forward, or even start to raise his arms quickly rather than simply turning on a light.
I guess it all depends on what you are going for. Good luck to you!
