I do practice on paper but I'm not good on a device

I won't disagree with you on that, but maybe you should practice a bit on paper, that always helps! and just so you know you don't have to be great at drawing, just entertain the cap out of the crowd! :)

But I suck

that's not it, you just need to make better animes, stuff that people relate to, or just look cool or make them laugh, you know?
