The Mickey Mouse and Minnie Mouse Picture is in the style of Monet and hand-drawn first and then painted in Photoshop. I call it Monet Mouse.
The Wild Horses are an example of chalk pastel.
The tiger is a watercolor using a wet and a dry brush technique
The Little Shop of Horrors poster is hand inked and colored in Photoshop.
The Into the Woods poster was obviously imitating the style of “Al” Hirschfeld the American caricaturist of many Broadway Playbills.
Here is another in my Play On Words Art Series: Mondrianopoly.
The caricatured tiger is drawn using colored pencils.
The long-tailed bird is chalk pastel on a black background.
