I mean, it's really not that terrible. Believe me, I know plenty of submissions that tried far less and succeed less. The lip syncing is actually pretty good to be honest. But yeah, not really a fan of tween animation. It can be good if done right, but here though, it really needs some work. The art and linework also needs some work in my opinion. The overall submission is nothing bad, it just needs more work.

But now my biggest problem here is not the submission, it's the fact you tried using your age as an excuse to avoid criticism. I'm sorry kid, but being 11 does not mean a damn thing. You could be like 8 on here, and still be criticized. The idea of constructive criticism is to help those in need of improvement, and watching them improve in the near future. So yeah, there is really no excuse to avoid being criticized in general, and your age especially is no excuse either. Plus, I know a good chunk of 11 year olds that has made wonderful animations, and put their all into it. All I'm saying is, never use your age as an excuse. It really is not ok.

And don't think I'm hating on you. From the look of the submission, it seems you have some potential and talent that could really shine one day. You just need to put your all into it, and try to make something wonderful. So yeah, I wish you the best of luck!
