I love the challenge! I spotted seven differences. 🙂

The ring in the headboard, vertical post on the left of headboard, pile of leaves(?) outside, wire running across top right of bed to table on the right, cover plate on wall, something white on left night table, phone charger(?). Got 6.

Well done if you found all of the missing items. There were actually 8 but you are forgiven in you missed the necklace. You needed to zoom in to notice that one 😉 Here is the solution.
