Actually, this has potential, although I'm not entirely convinced you really "sold" it here. There are a few little things I'd like to point out in hopes to help you regarding the requested feedback.
Style : I would say this has the 'feel' of kind of a hybrid between anime and something I'd expect from an old Ralph Bakshi film... say from the years around Fire & Ice or Streetfight... It's not bad, considering he was an actual pro' in the world for a time.
You have a few proportion details to work out, but don't beat yourself up. You're working with some influences from film-noire in your perspectives and that makes proportions a pain in the...
Audio: Again, from a point of film-noire the rampant use of footsteps is similar in theatrical effect to a heartbeat, so not terrible. I might suggest adding some heavy breathing, and since that doesn't require voice, anyone can do the part... literally.
And as to plot : The only confusion as far as I could see came with the blue-haired girl's body going over the edge. It would seem you were indicating a levitation, which might call for just a few frames of the 'levitator' concentrating or performing some semantic to induce the effect ( 'selling the shot and story' as they put it in the business)...
There could be a better hook for starting, but that's true of almost anything. Maybe you could try just a hint of why one wants the other dead. Is it a professional hit? Since she opened her eyes on the ground, was it just a hunt, intended to wound and cripple but not kill? Who might arrange such a hit, and is 'green hair' really that good, or did she screw up and let another person save 'blue'? This could be your cliffhanger for the next show, but a touch of backstory as to why 'blue' is being hunted or killed would probably sell a better hook than just plunging in with the running. Maybe a Yakuza or Mafia arrangement... Maybe a psionics guild (would explain 'green' and her penchant for floating around) etcetera... You wouldn't have to give the whole backstory away, just a few flimsy basics to build on later... like money changing hands, a little voice over from mysterious stranger to 'green' arranging the hunt / hit / whatever. Mentioning something of whether 'blue' has committed some underworld crime or sin... or if she just knows too much for her own good... You see?
And of course, if you have any question's you can find me most days with a PM. Anyone can. I can only suggest and hope that some of this helps.
