"There could be no-one there, ..."

"...into a razor-filled muzzle ..."

"... sleep, muscular, brown-furred monster."

"... through her blood-soaked fur."

"... propelled backwards in mid-leap, ..."

"... the red-haired woman ..."

"... a tall, grey-haired man ..."

"mid-thirties"

"mother-in-law"

Not my style of fiction, but most of these don't offend my sense of grammar either. I think "mid-leap" is the only one that slightly jars.
