Needs FURTHER improvement
Before I begin this review...Sheller, you honestly need to calm down. It's just a flash cartoon. No need to get all worked up and all angry about it. Do you honestly think that your "review" is any helpful? Constructive criticism would've been more helpful, if anything.
Anyway, on to the review...
Overall, I really am not going to nitpick on your tween animation, since you've been using this style for years. So by all means, just stick with it until frame-by-frame becomes your forte. Otherwise, there are no problems on that department, since that is your intention.
Otherwise the writing felt very stale and rushed, as well as the characters featured in this flash. I'm to guess that the humor in this flash is based on inside jokes among your friends. Sometimes that can be a good idea, and a lot of times, a bad idea. People are going to want jokes that they can relate to. Maybe I'm wrong on that end. You may have to correct me on that. Not saying that you should resort to jokes, like the ones featured in some popular flashes here in NG (with penis jokes, gross jokes, violence, basically anything ultra offensive). Over the years, I've noticed that you try to stray away from those kinds of jokes, and want to add your own brand of humor. However, as I have implied before, the humor is lacking. And I just didn't get any laughs out of it.
The singing on the opening, sounded off key, and the lyrics may need some adjustment. I'm very sure you want to come up with some silly lyrics that will make you go "WTF" and laugh. But it just didn't feel right.
While I understand that this is a pilot, a little more effort could be used. I'm very sure that if you do continue the series, and I hope you do one day, the overall show will not be like that at all. Just find some new material in humor/comedy, maybe change up the story as well as the characters.
I know I'm not exactly the best critic. But the only thing I can do is just give out some suggestions that might help you out in the long run. Despite what others say, I'd just continue on regardless. But please, consider changing up a few things before launching this series. I wish you guys the best of luck with all that.
