This would make a good series on Cartoon Network. Although be it a PG rating if you want the realistic drama.
Many youths are struggling with the ideals of unconventional artistic expression vs the demands of society.
A show like this could help give some insight to struggles artists face, the hardship of criticism, the feeling of betrayal when someone steals your work, or the feelings of self-worth when no one reviews your work.
Now being that this is just a pitch short, it expresses the idea quite well.
I feel like a sorta 'slice of life' for artistic types series with musical numbers in-between similar to how We-Bare-Bears do their montage.
A show about feels, goals, and hardship through hard work.
