How can I recover my iCloud pictures?

Circling back. Did you create a new Apple ID (You posted "logged in my new Apple ID"). If you created a new ID, your previous information (photos, purchases, etc.) are likely tied to the old Apple ID.

If the photos from the 11 were not synced, there is no way to get those photos. Follow these steps: https://support.apple.com/en-us/HT201472
