Answer: The second option is correct. The sentence with the comma.
Explanation: the comma goes at the end of “free writing” to indicate a pause. Up until the word “free writing” the sentence is not complete so a full stop or semicolon would not work. Semicolons are used between two complete sentences which are not already linked by words like and, but, or, nor, for, so, yet. The first option is also wrong because it uses “your”.
