The word "coos" seems a bit unfitting.
Would a creature with no face be able to express ideas such as "look", "smell", "taste", etc?
Because this is written in first-person, I'm worried about the amount of sophistication here, like TokyoKenshin said. Doe this character really talk and think like this? Hell, it's certainly possible, especially if it spends all its time alone in a dark forest undergrowth, but it's something to consider. If the character talks/thinks as the story goes on, the manner of speech will have to be consistent with this.
