Design a captivating hand-drawn watercolor clip art image of a family gift niche embellished with birth flowers. Customize the image for a family of five: a February baby (Violet), an April baby (Sweet Pea), a July baby (Larkspur), an October baby (Marigold), and a December baby (Holly). Enhance the image by including delicate watercolor foliage surrounding the birth flowers, adding depth and a touch of nature to the composition.
