I think the face is a bit too wide at the bottom. But for a one of the first times drawing with a tablet you did a pretty good job. Might want to try add a big color and shading to practice on that too.
Thank you for the points about the drawing, but as for what you said about "leveling up", it was one of my first tries using a tablet, so I didn't necessarily want to draw something from my head, but thank you.
