Design Competition

I will be entering the International Compost Awareness Week poster contest. This competition is sponsored by the Composting Council. The purpose is to design a poster to promote the benefits of composting. 

Entrants must use the words: "Compost! Healthy Soil, Healthy Food," and "International Compost Awareness Week, May 7-13, 2017."

My design is depicting how compost under the ground benefits the vegetables growing in the ground. The stems are hard to see in my sketch, but they make a Rx design to symbolize that compost is the prescription for healthy food.

The poster must be original artwork, no larger than 12" x 17" and 300 dpi, jpeg format.

I will primarily be using Illustrator, but will most likely use Photoshop as well, since the guidelines of this assignment is to use two applications. If I can find something more suitable other than photoshop, I will use that instead because I am not interested in using a photo for my poster. If anyone has ideas for other applications, or other ways to incorporate Photoshop, I would appreciate it
