Nicely done, her pose is solid and the coloring fits the character and does add volume to the body, the metals effect is good which fits the soft-cel-shading used on the all drawing. You used 3 zones of color in a very effective way.
Her visible arm looks a bit odd, as if her hand is turned differently than her forearm, her other arm or part of it could be visible at least a bit.
Did you use the Ziio for the line art ? I notice the DragonBall Z influence in the proportions and shape of her head and eyes.
Hi Mauricio, thanks for your honesty and for taking the time to review my painting.
I actually did a sketch of the basic shapes from photo reference, and then worked on her with my Wacom in Paint Tool Sai, using custom brushes shared by someone at Dev Art.
The general position of the arm was blocked from the reference, what you are probably noticing was my inability to provide proper depth and rendering once painted.
I will make a note of your comments for my future improvement
