I’m not trying to be an @ss but you’re in the danger zone at 750hrs.
Fly with as many instrument students as you can and try to fly with them in actual (when it’s safe to do so) and at night.
Hone your skills till you’re razor sharp.
Instrument instruction is a good deal more dangerous then basic flight instruction.
You’re spending a good deal of your attention inside being one of them.
Multi engine instruction is the most dangerous form of flight instruction as literally every multi engine student will try to kill you at least once.
With basic instruction in a simple single there’s nothing they can do to kill you above 1000’ AGL that you can’t fix if you’re sharp.
In a multi a Vmc/ stall/ spin is pretty much fatal no matter what altitude you’re at.
That and not every multi engine student is at the skill level they should be when you get them.
My very first ME student buggered up a crosswind landing when I wasn’t expecting it and we nearly ended up belly landing in the grass.
Never ever let your guard down in a twin.
It’s some of the most fun and rewarding instruction also by the way.
Be the best you can be before you report to the ANG.
They’ll wash out plenty, don’t plan on being one of them.
Best of luck to you.
