Designing is NOT as easy as you think

Arrrrrgh! I am running out of ideas and time! Oh sorry, that's just me, frustrated over a pile of design drafts. Today I have to design and paint a picture for my friend as a gift, and my deadline is this Sunday. My topic is suppose to be flowers, and my mom suggested me to do it in a cartoon combined with vector art style. I have already designed several drafts, but they are just not good enough. It's always the positions of the flowers! Positions of objects are always very important in an artwork, because they affect the way the artwork looks. Right now I am just staring at a blank sheet of paper, waiting for a miracle to happen. Who knows? An idea might pop up any minute from now!
