1) Tune down the colors, especially on the costumes. All the bright colored costumes are kinda cheesy. And maybe redesign them or use their current costumes.
2) Darken the mood of the show a little bit. Make it more serious and add some more drama.
3)Get some better characters. The Guardians of the Galaxy were so stupid: a talking alien tree and a talking alien raccoon.
4) Change the way the characters look. Make them a bit sexier. You know your cartoon is doing well if there are ships all over Tumblr.
5) Increase the tension between two male characters. The fangirls go cray for that!
6) It needs more tragedy. If it doesn’t invoke the feels then its not really worth it.
I really hope this is some kind of sarcastic dealie right here. Because if not you stand for everything I oppose in this world and
I WILL HUNT YOU TO THE ENDS OF THE EARTH
