One of my greatest inspirations is the amazing Art Nouveau artist Alphonse Mucha. His understanding and sensitivity to the human figure and beautiful contour inspired generations of artists. Follow this link here to see lots more of his work! http://alphonsemucha.org/
When you look at his figures observe the lines and planes that Mucha establishes to give such an easy verisimilitude to the figure. His figures, especially his female figures, have an effortless grace that transcends the image and the mind become lost in the "story" of the figures.
