Good job! The colors were well chosen, the golden highlights the traits, and the red shirt is not showing itself too much in the image, and if that is the goal, is reached. The ship, or whatever, is linked with the background. And the technique helps complete the design. Anyway, I loved it!
P.s.:My english is not the best, but I try, I hope you have understood. And one more thing, the design is somehow linked to any series, or comic, or movie, or TV show? I really what to know. Please, tell me if it is. I hope I've done a good critique. Thanks!
