Alien/Demon ReDo

I've been seeing a lot of artists redoing some of their old work and it inspired me to do the same. So I looked through all my old drawings and decided to re-draw an alien/demon portrait I did a few years ago. I wanted to add some personality and life to it. So far this is the rough sketch of it. I've included the old drawing for easy comparison. I gotta say, at the moment I'm pretty happy with it. :)
