Take a look...
So, did your photo crop up in Hogwarts castle? May we say... you all look amazing.
And remember, you can also catch up on our livestream, where the mosaic is also featured, and see if your photo made our digital celebration at King's Cross station.
Those signed up to the Harry Potter Fan Club newsletter will also be able to lookout for a downloadable link to the whole mosaic - stay tuned next week.
