Stonzee you need help on the cookie making?
If so - look at the layers.
Base: It is the one already in place.
Check the picture to see what is on top of that. You can see those layers if they are partly hidden by the top cookie.
Check the colors of those ingredients and also if those ingredients are in layers.
Add those then.
Top cookie: See if this is present. It is lighter in color than the base one.
Determine if it has jam or sprinkles before or after the cookie cutter was used.
If before - then the hole made by the cookie cutter does not have the sprinkle or jam or glaze on it.
If after the hole has them.
