monster sketching for ant

So my good friend Ant has been working on a death metal project of sorts and asked me whether I would be interested in doing some album artwork for him. He told me roughly what he wanted and that happened to be some monsters that were similar to the "lickers" of resident evil. It's always hard to draw a monster that doesn't have eyes without making it look like a varied rip off of Giger's Alien (which I am a huge fan of). Anyway, these are the first few sketches that I came up with, I did some varied faces at the bottom too, just in case he changes his mind about the monster.
