I feel that all the time, trust me, I know artist in real life who are my friends and are ten times better than me and it makes me really upset. But all I can do is practice. if you want to try to get better check out some guys on youtube when you have the chance. There's this one guy who's name I forgot but it starts with an "Sy" or "Scy" but the rest I forget, he's really good though. Also try drawing real life stuff like human bodies from photos and real life, it helps you with proportions.
