Is this a Draw.. updated

This thursday I played a fun game that came down to the following endgame. I was Black and was able to promote giving me the chance for a perpetual check draw. After looking at the game I wonder if there was a win somewhere. Probably not but I still wonder. Perhaps someone here can see it.

Update-----------

Sorry. It seems I did not clarify the position. White moves next. The move is the move played in the game. I know that White has a win here. My opponent did not see that and played c6. After his move is my question. Is there a win for Black or is this still a draw?
