I'd just like to offer some advice XD
While the vector is nicely done, I see that you're using 'paths' to vector lines. While that works on some inanimate objects, it's better to use 'shape layers' when vectoring living things like animals, humans, plants etc. It might take a bit longer but the result is a more crisp look, especially on the hair which then gets those nice pointy ends instead of the blunt ones. Keep it up! :)
