Good, that was the idea! I don't know if you'll get it but when drawing the tail i thought about an enemy in Devil May Cry 3 that carries a hughe ball of flesh and spikes, that the more you look at it, the less time you have before it explodes. So i went for something similar
Maybe the tail is full of liquid, or gas, or skulls and bones, It's up to imagination.
