PERSONALITY
Janeesh gets the majority of their entertainment from bothering others, taking on a villain persona in not only the dance world but their real life relationships. Janeesh's highly competitive nature can actually make them quite a fun person to be around once you get past the antagonizing.

VOICE
Janeesh's vocal range could go any way. They'd certainly strive for a "sexy", laid back sound in order to make their comments that much more agitating. Janeesh speaks fast yet clearly, occasionally elongating a word for emphasis but that's about all that'll slow them down.
A voice reference for Janeesh would be Dorian Electra's singing voice, where they put on a deeper voice that would be similar to Janeesh. Of course, Janeesh isn't singing all their lines so don't take this entirely as reference, just the range.

Janeesh is from India, so an Indian accent would be nice but is absolutely not required.
