Another option is the creation of a watercolour painting, based on photos.
It will not be finished during the event or party, but have everything and everyone in it that you want.
That painting will be created in watercolours and will have a manageable size.

The price for a Party Watercolour created with pictures is 750€.
They are created on 30x40cm 300 grs Arches Torchon, with a mount.
Cards are a possibility too.
