Critical comment I have received in the past: how can a 12 year old be an artist?

 One answer: be prodigious

Child prodigies have devoted a vast portion of their lifetime to a craft. Often times it's to an unhealthy degree.

So yes, if young Jisha spent an unhealthy amount of time on her artwork, it's only natural that she's good at it.

Health side effect: bone deformation during growing years. Whoops!
