This isn't pointed at anyone in particular but addressing a trend I keep seeing in fannish spaces. I'm going to tell you one of the most important things I learned in art school:

Never talk your own work down.

Don't apologize. Don't make excuses, and NEVER point out flaws.

I know it's tempting, especially if you can see flaws and they're driving you insane. If you know you were tired, if you know it's not your best. Don't do it. Present your work and let it speak for itself. If you have to make commentary, never criticize.

When you talk shit about your own work, three things happen: it devalues your work, it insults the taste of people who DO like your work (you are in fact talking shit about them), and it primes readers/viewers to look for flaws. You don't want them doing that.

On a long enough timeline, the world will knock your stuff down *plenty*. Don't you do it too. Be proud of the things you create, and if you can't be proud, at least fake it in public. If you really hate something you made that much, vent in private.
