Got a B- on the paper! some of the way you wrote the paper gives me the impression you understand what you wrote here. NIMS is based on ICS, and ICS is a system used to standardize the response to incidents. One of the main things is common terminology, which you digressed from. By not using that specific terminology (incident commander, command and general staff positions, section chiefs, etc), it makes me uncertain you understand the material fully.
The paper is a good effort.
