She really has evolved through the years! Interesting process to see, and you've really improved on drawing body parts, and natural shading. Style still feels a bit unpolished/sketchy/sometimes disproportionate, but with all this progress in such a short time I'm really looking forward to seeing how she'll evolve in just another year! :D In a way, it's like she's growing up through your artworks as well, she looks a lot more grown-up and sensual in the later pieces. Nice work!
