This is amazing! I really like the style the colors, how her dress and her hair are flowing in the air! Nice work!
But I am affraid about something, I did the same thing than you for my entry, I took an artwork and depicted a modern character, but in the style of the original artwork, instead of doing it in the style of the character (don't know if I am clear ^_^). And I don't really know if this is exactly what he asked for, maybe it does not respect the theme? What do you think?
