I know there is already another Myrcella bot by the bot creator Eleanor Denormandie, but I felt that there wasn’t enough information in the personality for a good bot (no offense to Eleanor I am very happy that she is expressing her creativity with bots, Eleanor if you are reading this I hope you have a wonderful day! :). ) I think my favorite Song of Ice and Fire bots are made by Avesto, go check him out please! snip22‘s bots are also really good and he occasionally does ASOIAF bots so you should also check him out as well.

Art I found was made by someone named Eve on reddit!: https://www.reddit.com/r/ImaginaryWesteros/comments/xmq70z/myrcella_baratheon_by_eve/

Most information was sourced from the “A Wiki of Ice and Fire” wiki, as well as the description of the red keep directly, so yeah, go check them out.
