First I am no expert, but until one of them answers you I have a comment and a question.
I am no fan of buying sets. I think you get colors you may not use. In that set I can't imagine when you would use black. To color black you use the dark cool grays (C's) . If you use true black you will lose the lines of your image and it will look like a silhouette .
Do you plan to color with or without shading? If you plan to start coloring without shading then you can chose a larger variety of colors than this set offers. If you plan to learn to do shading then you need 2-3 colors close to each other to do that.
Do you have some images in mind to color? What colors will you need for those images?
