What happen when danish gambit declined

Danish Gambit is one of the most common uses chess opening by myself nowadays and I really like this chess gambit because it is easy to use and very effective when it comes to positioning your pieces on the chess board. However not every time your chess opponent will accept the gambit and therefore you need to come out with plan B. Below is one of the chess game which I have played and win when my opponent declined the danish gambit and thus makes me need to work more harder than before to win this match.

The key to destroy the danish gambit is to move the black queen to the front of the black king!
