Create a vibrant tree design where the trunk is brown and solid, with branches stretching outwards. The leaves should be colorful, incorporating shapes like hearts and teardrops in various hues including green, orange, purple, and yellow. Emphasize a playful and cheerful spirit through the arrangement of leaves, making sure to overlap some for a fuller appearance. The background should be white to enhance the colors of the tree and leaves. Lastly, add a subtle shadow underneath the trunk to give the tree a sense of depth
