Put wax paper on the edges of the half sheet pan. They are there to catch any drips and will be removed later. Put one of the wafers on the half sheet pan.If you were unable to find rectangular layers, then put wax paper on the edges of a round cake or other plate.
Make the Filling
Put the softened cream cheese, sugar, lemon juice, Fiore di Sicilia, and vanilla in the stand mixer and mix until a spreadable consistency. You can add milk if it's too thick.
Spread about a fourth of the filling using an offset spatula evenly on the first layer. Cover with a layer spread filling on that and continue filling and layering until you get to the last layer. Press down firmly to make sure the layers are set.
Put the cake in the refrigerator with something weighing it down. You can put another half sheet pan on top and put something heavy on that. Leave it in the refrigerator for 12 hours.
Decorating
Divide the frosting into two microwave-safe bowls.
Put one of the frostings into the microwave for 15 seconds, or until it has started to melt.
Add enough of the blue gel color to get a nice sky blue color. Stir well.
Spread this on the top two-thirds of the cake with a pastry brush using horizontal strokes. Try to have any of the brush strokes showing.
Put the other frosting into the microwave for 15 seconds, and then put the green color in. Use a lot, stir, but not as completely.
Use a paintbrush, using vertical strokes to paint the green frosting on the remaining bottom third of the cake. Try to make the strokes look like grass.
Using your hand to protect the sky, lightly sprinkle the green sugar on the green frosting.
Put the pineapple ring in the center of the sky.
Sprinkle coconut into clouds on either side of the sun.
Use the chocolate covered sunflower seeds to make various flowers, using green seeds for the stems.
You can make a tree trunk using the black sesame seeds. Make a "frame" around the cake using sunflower seeds.
Let the cake sit at least 1 hour before serving.
