OH MY GOD!!! I only can stare in awe at this set (and wish for even the tiniest fraction of your talent). On a general note, I love EVERY SINGLE ICON in this post, but if I have to name favorites, it would 4, 5, 6, 7, 13, 15 and 16 from the set, along with 23, 26 and 28 from the extras.
And I'm gonna snag the textures you linked in another comment.
