Pics #1 and #4 leave the buyer guessing about the condition of the chainring teeth. In #1 the teeth look worn IMO.
You'll never polish them through the anodized finish. If you want to polish them, strip 'em with Easy Off and then you can shine to a mirror finish. Is it worth it? What do you earn at work per hour? That can help in your decision process.
definitely talk up the condition of the tapers and the pedal threads in your description; unless there are issues, then leave it off as many sellers do
Definitely include a pic of the caps and the condition of the allen wrench hole, if good. Also, if all 5 chainring bolts are original mention that, too.
