Two things that jump out are the rear cargo door & the position of the rotors.
On the CH-47, the rear cargo door slides into the ramp. Its not attached to the actual airframe at all.
As for the rotor blades, they are not that close together when over the fuselage.
Other than that, it looks good. Unless your sister-in-law is a chinook mechanic or pilot, I'd doubt she'd notice anything I mentioned.
