?! This isn't good! Yet I still lost ;)

This is fine. You can also take with the queen.

Qe5 and Bb4 are good for black.

?! You'll need to do a better job of intuiting where to move the lady. You overlooked Qd5, which is safe due to a simple tactic. Qe7 is inferior, but better than your move.

? Moves the rook where it wants to go. I think you missed the power of bxc in the variations.

? Bd4 wins right away.

? Only Qd5 saves you. Black is worse but alive.

? It doesn't matter at this point.
