Beautiful, richly saturated colors Laura! A couple of things to keep in mind: be consistent with the position of the highlight. It is in the correct position on 4 spheres and needs to be relocated on the blue and purple spheres. (Not that you have to do it, but keep in mind for next time). The shading on the left side of some of the spheres is too dark. Since that side is closest to the light source (judging from your highlight) the left edge is about a 3-4 on the tone scale. The area surrounding the highlight should transition darker as it moves away from the highlight as you have done on the green sphere. Nice job!
