I'm an animator and a skilled fancier of (creative growth) and learning curves regarding creativity.

Have you chosen a style of animation? Because there is objectivity in that.

If you can see the problems in your animation then at least means you can identify your mistakes.

3 months is extremely new no to the craft. Go easy on yourself.

Some of the best animators I know have their speciality I don't know many that can do VFX, character, cartoon, Disney, etc.
