Should I keep my Minecraft gaming username for my art handle?

I already made a lot of accounts using that name as I had aspirations to be a good MC Youtuber, but videos games don't do it for me anymore. I just want to draw.
On one hand I want to keep it as it takes me back to a happier time when I was 15, 11 years ago.
It doesn't have numbers or L33tsp3ak letter organizing.
