dont make flash when your bored.

The purpose to make a flash is when you feel a fire in your belly when making it, feel inspired basically. When you make a flash out of boredom, It can tend to be a very sloppy, truck-on-ice disaster. Before posting on newgrounds, think to yourself, Is this flash good enough for the community? Is it worth posting? If you answer no to either one or both, don't post. It will save you from a lot of mean words from the community. Next time around, try and take your time when making a creation, think things through, and most of all, don't rush. Another thing is that the flash portal is not for test animations, its for full completed content. One more thing, be original, that will please most people here. Have a good day.

needs improvement

Making a show on newgrounds is a pretty big project, one that I feel like you may need some collaborations with. Like some reviews here suggested, a preloader, practice, and a particularly interesting art style will help you in the long run. Newgrounds is home to professional flash artists and animators so they may expect more from your show than you can handle. Do some research here on this site and gain some inspiration from other things you see and watch. Have a good day.
