“Venom”style

This poster mainly uses the brush to draw several different shades of black, and then liquefies it. Actually, I don't know what it looks like, but this fluid material looks very abstract. Reminds me of the movie "venom" some time ago. I think you need to have some direction in the liquefaction process, like how the fluid here moves to get there, and it needs to follow the most basic laws of motion. If you're really casual about liquefaction, it's going to be messy and unaesthetic.
