Here's my take on the position: ;P
Black can't stop the pawn mating. And if - after c7 - he tries for something like Rd2 in order to give repeated perpetual checks (knowing that the King can't venture onto the c-file without losing the Q), then this only works for so long, as after the King finds a way to play Kb3 he can simply play Kc3 on the next move without threats to his Q. Black is out of checks at that point and will go on to lose.
