Well..
My knowledge of the story behind FF7 I can kinda grasp the picture. It looks like you got the basics down which really isn't much to begin with. Artwork still needs improvement. Yeah, Cloud..heh..little to say about the emoness, but the joke is pretty straight forward.
It may help to build up your art skills as you go along. Don't limit to just drawing alone. Use any of the tools that you may have at your disposal whether you create or borrow sprite, clipart, effects, etc. I hope this comment helps. Best of luck on your flash.
