Below is the same flyer with different mesh subdivisions. The coarsest mesh is at the right, smoothed in the center, and even more finely divided or S meshed (smeshed) at the left. When the meshes are switched to shaded working models you can see what effects the different meshes will produce. These will affect your textures and lighting will affect all.

Below are the meshes, smeshed at the left, smoothed at center; at right I've switched into edit mode so you can see the pink dots I use to adjust the shapes.
