Confirmed. Adding such sensory detail to narrative descriptions is pretty easy to do in American Sign Language (I can't speak for BSL or others, though French Sign Language is pretty close to ASL, from what I understand).
I'm no longer good enough with ASL that I can do all that simultaneously (I'm a native speaker as a result of 8 years at a school for the deaf, but use spoken/written English all but one or two days out of the year).
