Citrusy just sort of looks awkward, which is something you also need to consider.
Citrus Creative is nice, solid alliteration at play.
Citrus Studio, Citrus Creative Studio are both decent as well.
Definitely no Bunny.
At the end of the day I’d go with Citrus Creative, though even simply "Citrus" would be fine. Then in your tag you could have "A Creative Studio".
