Who is winning here? What would you do?

In the actual game, black resigned, but I don't know that he should have.
It doesn't look like he is winning, but I think he still had chances enough not to resign.

Edit: This postition is black to move.

Black probably shouldn't have resigned so early, but being down a pawn already and the eventual loss of the d6 pawn, white should have a pretty easy win.

resigning here is way too premature. I think white has advantage but its far from easy win.

something like 1...Rg7 Rxg7 Kxg7 Nd4 b5 followed by ...b6 and black has some chances. or maybe 1...Bc8.

black should not have resigned.
