Character Design Project: Odin and Alien Abody shapes

Based on Justin's advice on trying out with the basic shape layouts for my Hero, I gave it a go. From my synopsis, my hero is Odin, the top gun God. Since being the highest rank of all Gods, Odin has a strong big body structure so I've started shaping out big muscular body shapes of him. As for the alien, I was playing around different shapes as well as the legs to see what I can come up with.
