It is not a bad spot to c-bet, you have 2 opps but they both checked and the flop is a relatively safe one.
Your bet size however is too small, you want to discourage draws from chasing here, I would bet 2/3-3/4 of the pot

I make it 120 preflop and as played I'd bet it a bit harder, say 180 or so. As played, I give up once my flop c-bet gets called. It sucks to fold to that small bet on the river but I don't think you have any choice.
