wait, you're 15...
You like to draw, huh. keep it up and someone will pick you up for their company, like studio ghibli, but be patient, we might be talking years here so be ready, lose your expectations completely, and always aim higher, but stay greatful and don't forget how much you're improving, what I mean is always compare yourself to yourself, never do it for someone else unless you want to, and always do it for fun or then you do it out of something else like for money or idk... it'll become a chore and you're gonna hate it ._.
AWEZING! AMASOME! cool, as heck..
