Yeah
You'll never make decent flash's if you are saying "if you don't like it.. etc etc"
Bad Reviews should encourage you to do better next time.
I like it that you want to make a good flash. But I don't like it, that you want this as a good flash. There should be some more animation or better drawing. More variety in your flash. Add some more colors or a background. Add a body or some arms to have some body language in there.
Keep working and don't let you down cause criticism. Criticism isn't bad. It helps you to get better.
