If people want to appreciate you for something you’ve created – even if you see flaws in it – let them. It is entirely OK to be appreciated & recognized for the things you create even if you’re better now than you were when you created them.
Don’t disparage your work just because you can see flaws in it. If it’s obvious to you what you could have done better, that’s proof you’ve grown. And that’s something to be proud of. And if you created something that people admire, that’s something to be proud of, too.
Don’t deny yourself the recognition for previous accomplishments just because you’ve improved in the time since you accomplished them.
