Critiques might be that zodds hand kinda blends into the background too much. As thats a mood panel you can have some fun with the color (keeping in mind its meant to be brooding and/or ominous). As for the others the colors are a tad plain, , the sky is all one color (a common mistake), and while a base color is there, there isn't much other variance in color to account for lighting conditions...
Keep it up.
EDIT: sorry, was judging some things that weren't done yet, my bad.
No problem, photoshop can swallow you up. I'm supposedly certified and have been using it for years but I still find new things in it all the time (don't tell adobe )...
