Rick very nice drawings there. I really like the head on the Alien. Very good hand shading there on the front of the head just before the mouth. Personally they still scare the hell out of me. Its something about all the bone shapes and the fact that they have no eyes. Very creepy. You've done a really good job representing them.

Ankalagon, good spotting but it might be a good idea to just post a link next time. Also get the artist permission before posting a pic of there’s. Its good form. I'm not jumping you. Just pointing out its a good ideas to fallow.
