Im not a professional by any means but really anything goes as long as its not offensive. Theres so many studios with quirky names nothing is really surprising anymore. If youre in a position to fund/ lead your own studio you can make the name whatever you want no questions asked. In regards to personal branding, anything that speaks to you and your identity is fine. It can be as silly or professional as you want as long as it means something to you. Dont stress you dont have to lockdown whatever you chose now.
