The white center is now very strong. Black has two main options to counter it.

6...Nc6 attacks the d4 pawn. This pawn cannot be pushed as the e pawn would be left en prise.
6...c5 is far riskier. After 7. d5, Black can be strangled. This game is going to be very tactical.

6...Bf5 is also possible & keeps the option of ...c5 before ...Nc6, but it tends to transpose into 6...Nc6.
