You're right we can't change usernames, but we can create as many alternate accounts as we like, each with a different username (and many people do so).
I'm glad you're satisfied with your name/profile/bio, and I wish you lots of success improving thumbs and headlines.
And huge props for exploring Fotor, Canva, etc. and aiming to elevate your photos, and I'm grateful to have inspired any part of that.
(grin) I encourage people to stalk my blog, there's lots of great value there, free to soak up. I appreciate you reading my work and I appreciate you leaving such kind, encouraging comments, it may inspire me to post again. :) Keep being you as well, and #KeepRyzing ! 🙏
