Final answer:

Step-by-step explanation:
The two features of the new constitution that Anti-Federalists attacked and criticized the most were the concentration of power in the Legislative Branch and the lack of a Bill of Rights.
The Anti-Federalists believed that the Legislative Branch had too much power and that it was unchecked, which could lead to tyranny. They also argued that a Bill of Rights should be included in the Constitution to protect the rights of citizens and prevent a dictator from exploiting them.
The Federalists, on the other hand, believed that listing all the rights in a Bill of Rights would be impossible and that the absence of a Bill of Rights would not necessarily lead to the violation of rights.
