I really like the feel of #6, #20 and #22 but feel like they need more whimsy, more femininity, but in a young, flirty way. Think Sex and the City, Manolo Blahniks, Pam Am (the new show - for a little bit of retro feeling - just a touch).
#2 and #1 designs - I like the idea of a feminine figure or silhouette but it needs to be less identifiable (race, ethnicity, features) and more iconic.
#8 and #9 designs - way too mumsy. Needs to evoke more of the single gal - independent, flirty, etc. - less soccer mom.
