This is a wonderful show of improvement. I still like the Futhark that you used in the original but the shading that you were able to do with the new version of the picture is nicely done! I don't know if you were trying to go for the skinny and muscular look but it, to me, looks like the character is anorexic.
TBH, you don't seem to have changed all that much. A little improvement, some better anatomy and posing, and superior photoshop (or whatever you use) skill, but your style looks mostly the same. Helps that the 'before' one wasn't embarrassingly bad, too.
I always wondered about the combination of runes and the English language. You've gotten better, but I remember when you made the first one. I followed you then because of your amazing grasp of anatomy, so I'm not shocked you're better now.
