Hey, there's nothing wrong with drawing MLP ^-^
My best friend thinks Adventure Time and all cartoons are stu.pid and I love cartoons. But we can get along... Everyone's opinion is different, there's always going to be someone who doesn't agree. But you never asked for their opinion, so that makes those invalid. ^-^ Real friends are encoraging people, remember that...
I'm just a stranger but even from this sketch I can tell you're great at art :D

i-i get bullied by my whole class since 2 years -im crying...-

who cares what anyone else thinks? people that matter don't mind and people that mind don't matter. but maybe that person doesn't deserve your friendsip. we love you here!

who cares? u like mlp... most people i know like mlp, my cousin loves em her friends to... make a joke back to the bullies.

Bully: dumb little kid like mlp? Hahaha!
you: Yes I do :) And I draw them mighty fine too! Un like some people who have hooves for hands :p

I draw mlp at school all the time. My freinds nor anyone has no problem with it (but they do when I draw "innapropriate stuff"). At least, that's what its like at my new school. My other school never wanted anything to do with me. So, on one day, a group of friends came to me asked if I liked mlp and I said yes and now I'm freinds w/ some of those people who didn't like AND my freinds! Seriously, If people laugh because of that, ignore them, that's what I do, or at least convice some to watch and like the show.
