To show off. And maybe to get a few criticism on how to make my piece a little better.
Happy?
Not really, that doesn't answer my question. Why would you want criticism on something that isn't a reflection of your abilities as an artist? You made a half-assed drawing, didn't like the result, and instead of identifying what you don't like about it and attempting to turn it into something you're proud of, you decided to "show it off" instead.
If you want to improve your art, the simple answer is
put more effort into it. Put everything you've got into something and wait until it's as perfect as you can possibly make it,
then show it off. That way the praise actually means something, and the criticism is actually relevant to your skills rather than your laziness. You're never going to improve by doing stuff like this.
