I've never left a necessarily 'harsh' review before so forgive me if what follows this comes off as cruel or discouraging.
The art and colors are awful. If you're looking to make an animation that you want some genuine attention and recognition for- you gotta study. You need to learn some body and geometric construction to just get a foundation at the very least. I know flash takes a lot of time to get used to but big chunky linework is NOT what you're limited to.
Tween reliance is a crippling thing and you need to learn about keyframes to remedy that. Rick & Morty use some tweening but do it exceptionally well- study them.
Voice actors were clear enough to pass for a beginner animation but they were ultimately flat and lifeless. Look up Yeti and Snowball microphones- inject some personality into your dialogue. Getting a start in animation is incredibly difficult but you have to put blood and sweat into it if you want quality work.
