Digital Art | Color Adjustment Scene

For our 3rd Project, the Digital Art students are combining 4 images. One must be a bright landscape, the 2nd is an object that is black and white (preferably with white stripes or something with distinct separation between the black and white areas), the third is a flying object, and the fourth is an image of a tree. Adjustments that all students will make include changing the white areas within their black and white object. Using a color adjustment layer on the leaves within their tree as well as adding shadows to keep the image looking 3-dimensional.
