Was machst du in deiner Freizeit?

Hallo! It's me again…

I'm trying to answer the question:

Was machst du in deiner Freizeit?

My answer includes "I like to see vintage movies and write novels" so I'm saying (this is my 8th day learning German):_

Ich mag alte Filme (/Ich sehe gern alte Filme). Ich mag Romane zu schreiben (/Ich mag es, Romane zu schreiben /Ich schreibe gern Romane).

Is that correct?

Danke!
