Finding Ideas for Presentation Boards, HELP?

I love design but I can never find unique ideas for 2D presentation Boards. I always see the layouts from other people and they look so sweet. My designs are decent looking but they start to suck whenever I start putting text and color and shapes on my boards that they dont look so good. Any ideas on finding unique ways on creating presentation boards in Illustrator???

This is for my final thesis project and its a new garden utility cart so im thinking green colors thats all I got! please help me! :neutral_face:
