@keac Ok, ok...so I've been hearing a lot of good advice from other creators here: Turn your envy into admiration or inspiration...work your ass off to get better...attend lifestreams (this actually really helps!) and watch tutorials...
There's been talk of how some people are just popular and no one really knows why, but the thing I find myself going back to is this:
Are you proud of what you do?
I'm not talking about the: "I'm really good" which leads to "but then why does so and so creator have more subscribers than me." I'm talking about when you look at your story and your art, do you feel genuine pride for your work? Not your work in comparison to someone else's, either, because then it is still about the other person.
Your artwork; your story is your own. It is separate from everyone else's, and that's how you should view it. You created something, and that, in itself, is amazing and good.
One other thing that has helped me fend off any unwanted envy is reaching out to the creators I admire. Let them know you enjoy their comic (omg do fan art!), tell them you admire their style. We are all creators and we all need encouragement, no matter how many subscribers or views we have. The more you reach out (and hopefully are graciously received), the less envy you will start to feel, because it will eventually become happiness at the success of a friend.
