Grey Alien project

Anyone who's seen the bulk of my work must have worked out by now that I kinda like these fella's.  This is the beginning of a bigger project I'm doing where I want to realize all descriptions of what our otherworldly counterparts might look like.  I'll post more as I develop his body and the other characters as well.  I will be using this guy as the base to do the rest, and might do a skeleton as well.  It's really enjoyable as it's less about designing something we've never seen before and more about refining subtle forms until it looks real.  That is my goal anyway to create a realistic depiction.  Enjoy  :)
