d5 just loses a central pawn for you. He didn't see it but he had more attackers than you had defenders. Once you got your queen next to your bishop your bishop was trapped by pawn moves he missed. I didn't like your queen move to the 7th rank. It seemed like you weren't sure what to do. I would have moved my king rook to the active file. None of this mattered bc he gave you his queen. If you want to really improve play 15/10 or 30 minute games. It will get you thinking much deeper.
