It's a very good piece, it wasn't by chance I clicked on it in the 1st place the composition, coloring, which I envy you for color palette, and the trace is well executed on almost all of her body, nonetheless if you allow me to point out something that could improve, is her legs, I personally find them way too skinny. Unless this character is explicitly this way, I would really like to see her on the classic heroine prototype, with nice and full roundy legs and hips, compared to the rest of her body, her legs even look below the expected average as I said.
Nice job dude, really nice. I'm a big fan of Invincible and Alphonse Mucha's style and you've put the 2 together sweetly. Shading on the legs and especially around the knees is excellent. Plus the hands are well really well done too. She looks nice and elegant.
