In terms of finances, I'll have to wait until I can earn enough money (still a senior in high school, and I don't have a penny to my name :P) to do anything with my ideas. I might start it off as a Kickstarter, that way I can pay whoever is helping me with the project. I'm aware that any type of animated series requires money and time, and right now I have neither. Until then, all I can do is build the concept itself.
I guess my biggest concern is getting the feedback I need to improve my work, since it's hard for an artist to look at his work and judge it objectively. I can see why sharing ideas online would be risky, because then I run the risk of my ideas being stolen. Nevertheless, I need a way that I can get constructive criticism from others.
