You can do better
This flash sucked. But I can tell you had a nice idea for it in your minds eye. You need to be more modest about what you can do. You have some drawing talent, but I think if you try just a little harder you can do better. You dont have to draw awesome, sometimes people just cant draw but they manage to animate and present it in a way thats very enjoyable to watch.
You need to figure out how you could improve on what you just did. Figure out how you could redraw some of your stuff to look kewler and you need to put more effort in the animation.
Again, you had some cool ideas. But if you want to make a flash series out of this, I think you should try harder and put more effort into it. The yellow ranger there does look like a dude. You can do way better to make that look female.
