I like where you're going with your marks, especially # 1 and #2
we'd like to see more color and personality. It's essential to make the mark acceptable for both females and males alike. these may be it at the end of the day, but they seem a touch too rigid. Maybe even adding some nice non-pastel, bright colors may make them feel more feminine.
Think of a novelty/craft beer drinker, likes phish but also hip hop, who loves to ride his/her mountain bike in the deep woods or go on a steep hike.
In regards to my first comment, I didn't mean to say non-pastels. Pastels are fine. Earth tones is what I'm going for, but rich, energetic earth tones. Like the brown you have, maybe some softer mid greens, etc...
