Looking for puzzle: 2-3 moves for checkmate

Yes, it looks more suitable for me. How do you create puzzles? Do you take some patterns or just throw pieces on board and see what you can do?

Qd5+!! Qc5+ (sub-optimial) b6#
Qd5+!! Qxc5 (sub-optimial) b6#
Or you win a Queen in the optimial line. After the royal fork you can promote your passed pawn, and have a winning endgame.
I got this puzzle from a video and modified it.

I mostly have an idea, then try to turn it into a puzzle. I try to eliminate all other lines that gives an advantage to solver's side that's enough to win with perfect play, and I add pieces to do that. That's why I have more pieces usually. That's my style. And sometimes I throw pieces randomly and then suddenly I make a puzzle, even if that wasn't the goal. It's just a skill I guess haha.
