A Quest Denied

I think I'm getting better at digital painting! I'm not too sure though, I guess I'm overly critical on myself about my own drawings. Are there are tutorials or techniques I could look at for digital paintings to help me improve?

That said, I am pretty happy with how this has turned out. I wanted to do another action pose for the demon character I've made but felt like it needed something else. I went through a few iterations of poses and eventually came up with the idea to have a demon sucker punch an obnoxious 'hero' in the face!

Hope people like it! I had fun doing an exaggerated expression on the hero.
