Similar to other people, I've join several discords and connected with other creators through those. I've made some connections via the forums as well, and that has definitely resulted in a few collaborations. But most of my interactions have been from discord. And it's just fun stuff -- memes, gushing over each other's art, gushing over fandom stuff, every day life. Even had a few meet ups.
With that in mind, I'm not really intimidated by other creators, even if they do have larger audiences. Having made friends with other artists and met them in person, both featured or otherwise, I know what they're human just like me. They've got their concerns, their aspirations, their desires. Honestly, all I ever feel when I see a big-name is admiration. They might not have everything figured out, but they're doing well for themselves, and that's awesome.
I feel like once you've made those deep connections with other artists, big and small, and have seen things from their angle a bit, any feelings of intimidation go away. Or maybe it was never even there, and you don't even consider it because...well, why should you?
I don't mind healthy competition and playful rivalry though -- I think if we see someone who's doing well and are motivated to get to that level and improve, that's pretty awesome.
