LOL - as I said, I don't mind critique/feedback. I just won't always heed it
As for the gravity effect -- I did actually envision it as a 'mass reduction' type of effect (not that that is any more 'realistic than neutralizing gravity). But with the 'tesser' ability, I see it now as some sort of 'partial dimension shift', so that some of their mass is no longer on this plane of existence, which of course means that gravity affects them less. Probably until the majority of their mass comes from their wings.
Of course how they could survive that way -- who knows
But it would mean that they would not be able to 'directionalize' it as you are suggesting.
