#1 #2 is too scary and evil.

I like the second one

2

1 I like the color red and the gauges, 2 looks creepy with those eyes and teeth, maybe you're going for creepy.

the design of one with the head of two

That's scary 😆

2 reminds me of Vecna from Stranger Things https://blossom.primal.net/0ff95ef2255543164e1a85cddaf70f8d94955f78b88ccaae87a0a15818f5ffc8.png
