This afternoon, we went to a nearby park for a sketching lesson. Everyone set their easels around a model dressed in a leprechaun costume, balancing precariously on a porcelain mushroom stool. In case we became hungry, our teacher even ordered pizzas for us. I need to add more details to my artwork before submitting it. Take a look at this photo. Can you help me find where these items are?

Hidden in the puzzle include five four-leaf clovers, three symbols of Pi, three single slices of pizza, one fishbowl, one screwdriver, one tennis shoe, and one broom.
