Not to disapoint you, but I have seen this general structure and the inital moves plus queen domination in a (very good) endgame posted here somewhere in the last half year. Not easy to discover something new in endgame studies. Doesn't mean that you cannot make a new ending with this theme, just may have to work a little harder to make it stand out.

Bd6 b7 dude

wait nvm

nvming, nvming, nvming ... OK, done!

Cool Tactic! I'm a sucker for a nice one.

I just created a tactical endgame. White to move and win.

What about 2.Kd6 b3 3.f8=Q b2 4.Qh8 pinning the pawn to the king? I think after that the queen can get closer with checks and pins, eventually bringing in the king as well and winning the pawn.

I checked the position in the Nalimov endgame tablebases. Nighthawk's puzzle is correct. After 2. Kd6 white must accept the draw for all the lines are drawish. Ascertain about it yourself.

I failed to factor the knight into my calculations. Okay.

 Here's a new tactic I made.

I think I just created a chess Study! White to move and win!(Oops... there's more than 1 right answer, but try it anyway)

very nice

This is a crazy hard tactic from a real game! Good luck!
