Did you send anything else? consider anything you sent to them leaked. They can use your ID for their other scams to make themselves appear legit and/or sell it. Although anything like taking a loan probably won't be possible with just that, I still think it's better to keep an official report of what happened to relevant authorities in your country for the sake of keeping a record. Just in case, also pay attention to some points where they can try to approach you and/or harvest more info e.g. social media.
