Hmm I think it depends on how you look at it, if you feel like "I'll never reach this level" or "my art sucks" then it's better to focus on your own art and try to improve it or maybe to use it as a motivation to do your best, doesn't have to be the same level of skills
It also takes time to improve your art, but using references + tutorials helps you get there faster, and you'll start to understand how to draw more consistently
