/lit/ - Literature

/lit/ tourist here, I've been editing the same chapter for the last 4 or so sessions I've worked on it. Most paragraphs have about 5%-8% pronoun usage (I, my, mine, me, it). Am I just being too unsure about overusing them? That being said, scanning through my paragraphs time and time again did help me come up with possibly more interesting writing to replace the pronouns with.
tl;dr, I guess my questions are
Am I overusing pronouns? This chapter only has 3 characters, the protag, his cat, and the world as he moves through it.
Is there a good balance I should aim for between pronouns and the rest of the paragraph? (like general % usage maybe?)

In picrel paragraph 1 is 188 words and paragraph 2 is 122 words.
