Some thoughts.
Good start on a larger scale figure.
They eyes, bane of face painting, could use some additional work. The irises are not equal. Trust me, I know how hard this can be. I'm working on a bust of Joshua Charberlain as a gift for a friend. One thing I was taught was to look at the face in a mirror to get the eye alignment. It's like when you get you hair cut, the barber/stylist is looking in the mirror, not directly at you. I don't know why, but it works.
The demarcation between the yello and black could use a bit more attention. Just a quick line of black along the edges and you're home.
Hit the bust below the face with dullcoat. Everything looks quite shiny. Of course, that could be the flash creating excess sneen.
Finally, try to pick up the highlights and shadows a bit more. This can really bring a figure to life.
Keep up the good work.
