Wash and thoroughly dry all fresh fruit to prevent moisture transfer to dry components.
Melt the milk chocolate chips in a microwave-safe bowl in 30-second increments until smooth.
Place the bowl of melted chocolate and a bowl of candy hearts on a large flat serving board as focal points.
Arrange the sugar cookies and macarons in a decorative pattern around the bowls.
Group the strawberries and raspberries in clusters to provide color contrast.
Fill remaining gaps with chocolate-covered pretzels, truffles, and marshmallows.
Scatter pomegranate seeds and any remaining small candies over the board as a final garnish.
