I would say that the top tools I had to use are Blend in the Option button, Pen tool, and the Shape tool. I used the Pen tool for creating the shape of the flower and the little cut on the lily pad leaf. I used the Shape tool to create the lily pad leaf, ripples and circle spots on the water. Finally, the Blend helped the colors of the flower and the leaf to combine and look complementary to each other. I had lots of fun creating this project, especially making the flower. The way how the colors and shapes fit so well together brings satisfaction to me and messing around with the colors of the background.
