That is plenty for a mirror box, only thing I would add is crab shell powder or a sachet powder for reversing work along with Agrimony as it is known for it’s reversing ability as well as it’s use in breaking curses that are already in place.
Take the stuff you mentioned and make a packet out of the person’s photo. Set it in the box and place some agrimony and powders over it, seal the box, place a ring of powder around the box to contain it and burn black candles on the box.
You can then either take it to the graveyard and bury it asking the dead to hold this person down and to pull them down closer to their death the more they attack or take it into the woods and bury it in a deep hole with a heavy rock on top and then cover with dirt, ask the spirits of the land to hold your enemy in place and keep them from reaching you. In both instances be sure to leave payment and offerings to the spirits and thank them for their help.
Follow up with a strong cleansing and forget it ever happened.
