Oooof, I really feel for ya' on that one, I get this feeling too much, also.

I think with social media it's really easy to fall into the trap of jealousy. Trying hard to be happy but it's easy to slip

I feel that but a lot of artists plateau for a little while before they find something that propels them to the next level. you're doing amazing! <3
I love all of your art. <3

It's kinda funny how even the best artists do this still. No matter how good someone is there's always something in someone else's art that makes em think "wow that's neat, I wish I could do that".
You're easily one of my favorite artists and I hope to be able to draw even half as good as you someday. I keep forcing myself to just do small pieces instead of stressing about finishing anything just so I end up doing something at all.
Maybe try writing down the things you do well and see if that helps prevent focusing on this kind of thing. I love the extra effort you put in to the patterns on your characters and the designs you make for clothing. You do shading and very well. It's great that you can do art well with lines and without. Love the work you've done with colored pencils. Feels like you can do multiple styles effectively. But yeah maybe try writing things YOU like about your artwork and pull it out and read it once in a while.

Jealously and envy are two very negative and hurtful feelings an artist can bring upon themselves...that and self-doubt...
I'm very hard on myself, always listening to the negative voices in my head telling me I'll never be as good, as talented like other artists when in reality I've grown and improved so much....

Dancing, you're an absolutely amazing and damn good talent artist, who helps inspire and motivate other artist to grow and flourish

It is very easy to get stuck in a negative loop. I don't know if this helps but I love your art. It's always a nice part of my day coming home from work and logging on to see if anything was posted today. ❤
