I have improved.
I can only get better from here.
There will always be room for improvement.
I have learned many lessons from my mistakes.
The only way to go is up.
Remember these when comparing your art. Maybe you're looking at old art, maybe you're looking at your favorite artist's work. Just remember that what you have accomplished is great and where you've come from is amazing. Your best is enough. You tried your hardest and that's what matters.
Sometimes I need to sit back and remember that sometimes it's not the destination that matters, but how you got there.
Enjoy making art. Enjoy being creative. Don't look at your work as if you were ashamed of it. be proud. You put time and energy into what you made. Love it like it's a child. It IS your child. There's no need to compare it. You made it and it's beautiful. That's all that matters.
Sometimes you need to go back and look at your old art. Don't get upset, just laugh about it. Laugh, because you've improved and what were you thinking when you drew that? Who cares. You liked it then like you should like your art now.
Love your work.
