"should I give my raw files to my graphic designing company after completion of my designing art work, as I am worrying that any one can use my raw files for his own portfolio, as it is the only proof that the work is done by me. For brochures,logos, posters ect. are all arrangement based work that a client can ask for, but can they demand for caricatures,illustrations or other skilled and talent based works' raw files which I had made for them?"
