Create an ultra-high resolution 12K mixed media panorama showcasing the life cycle of a tree against a pristine white background. On the far left, begin with a hyper-realistic acrylic painting of a seedling, each tiny leaf rendered with microscopic detail. As the image progresses to the right, transition through various artistic styles and media: watercolor saplings with delicate, translucent washes; a young tree in colored pencil, capturing the texture of bark and individual leaf veins; a mature tree rendered in intricate pen and ink, showing every branch and shadow; and finally, an ancient tree on the far right created from digital fractals and generative art. Incorporate scientific illustrations of cellular structures and DNA helixes subtly woven into the foliage. The roots should morph from realistic renderings to abstract data visualizations representing ecological networks. Seamlessly integrate the text "ArtGuru, Professional AI Artist at your service" using a custom font that mimics tree rings, with varying thicknesses to represent growth over time. Apply advanced texture mapping and 3D rendering techniques to create depth and dimensionality against the white backdrop. Use high-fidelity color grading to unify the diverse elements while maintaining the purity of the white background.
