The first image is the first file I created in Illustrator. The second is the improved design I did today.
First, I used the image trace tool on the reference image. Then, I wanted the water to stand out, so I used the pen and gradient tool to trace and fill. I think this image could be used for showing facts. With the creek being a gradient color text would show up well. I think the new images is better because it has more detail. The changes I made helped the design be more recognizable as a creek.
