so.. someone requested a graphic, and I worked with him through pm he said it was looking good and i could get 15k for it
but now he's been inactive for a week, and i haven't gotten any tc
should I report and if I do so, would toribash force transfer the tc from his account?

Depends on the amount of proof and such.

Normally nothing will be returned UNLESS you actually lost tc or items.

You also have to have sent him the art without payment in order for it to even be considered a scam.
