Character Design Project: Photoshop Alien thumbnail

Today after taking on Photoshop Phil's advice on getting the proportions right and making the character in 3/4 view full. I focused on creating another alien thumb but this time trying to add the viking traits like big build and muscles etc into them. I've created this guy, which looks a bit "The Predator" thing, first this was done without Pen pressure added and later refined with the Pen pressure on.

refined- Pen pressure added and without thick lines

Original- quick drawing without pen pressure
