I like your mysterious and fancy theme!
I like the main colours you used "Blue, yellow, black, white, brown" these colours used really pops out, and the colouring is so GOOD! Plus the shadings.
I especially the theme, it's such a clever design :)
There is two things that I would change, and that is to have the mask split in half, showing at least one part of the face. Another, is having a pet, perhaps a eagle would fit?
I hope my advice has been helpful to you, and keep up the GREAT work! :D
5 STARS!
