Sweet! Love how these are designed from scratch and the attention to detail.

I'm product designer in a competitive industry by day so I'll give feedback from that perspective. Forgive me if it's not the straightforward answer you're looking for and I sound a bit preachy, ha.
From a purely aesthetic standpoint I like the Mulan design, but she's a badass and I'm asian so there could be some bias going on here.

If you ask me which one I'll buy - it's hard for me to pick without seeing the design in context - like overlaid on a real scarf and preferably worn on a human as well. Opinions are formed on impulse based on the information at hand. People are more thoughtful when it comes time to part with their wallets and will base a buying decision on a look that is most suitable for them. I can tell you right now that I like the Mulan design, but if I see the Snow White scarf paired with black leather jacket worn by an attractive asian lady, I might think "Hey, I can totally pull off that look, this scarf is so totally me!" and suddenly the Mulan one doesn't seem like a reasonable choice.
As a person buying online all you have to relate to are photos, stories, and an imagination. So it's helpful to provide as much information as possible, even it you have to fake it via photoshop, to inspire people to see themselves in your products. I think it's important to figure out your target demographic, where they shop and what they wear. If you are investing time/money printing every design in batch and hoping it will sell, make sure your target demographic will have buying power (!!!), and ask those guys for their opinion.
Personally I would ask people who shop on Etsy/Threadless/Society6 on what styles they like to wear, as those are the people who care to spend money on artistic, handmade fashion. And then build your brand around a particular look - so maybe it's not Snow White scarf in leather jacket but Snow White with a cute eco fleece sweater!
I hope that makes some sense.
