This is a really nice picture, but a lot of people use this pose. So it really isn't original. I've seen is all over DA. However you did do a nice job on the background and did an excellent job on the color scheme so I'm giving you credit for that. I like how you made their hair it's really nice. You've drawn his muscles quite well if I may say so. I like how the light reflects onto the cape. So you did a nice job with the lighting. I would definitely like to see more of your work because you did an excellent job on this.
