The terrain and the detail on the shield and tail really pop. My only criticism is that the left arm (our left, her right) seems a little jagged transitioning at the elbow, which could be fixed by just having the forearm angled a little further forward or back.
But this piece is great! I love how you were able to get so much detail in the hair and eye, while also covering up the mouth in a way that makes the expression a little more inscrutable.
