Design a hand-drawn watercolor clip art image of a family gift niche adorned with birth flowers representing each family member. Customize the image by selecting the birth flowers for a family of five: a January baby (Carnation), a March baby (Daffodil), a July baby (Larkspur), an October baby (Marigold), and a December baby (Holly). Ensure that the colors are vibrant and the composition radiates love and warmth.
