IMHO, you were a student and had an instructor who was in essence the pilot responsible. That should mitigate the downside of the crash. As you also know due to a head injury, you need to ground yourself and will need to be cleared per the FAA process. May take a year-- friend of mine who flys a G550 had it happen to him.
A future employer will look at it and probably just call it a training accident---their chief pilot will fly with you and he will make the call. Good luck!
