Here you go 2 scketches based on your brief where you can ask for any changes or make any suggestions. Shapes are very simple and without small details, allowing the small size reproduction like biz card without looking cluttered. I've made a sunrise scene, that symbolizes hope and a new beggining, having the little bird protected by the tree in a calm and peaceful position... made the option with and without the sun to allow you more choice. If any sounds promising, I'm at your service till the end of your contest. Wish you a great evening,
