The concept is interesting: create portraits or landscapes with numbered areas to color. It's known, that's called paint by number. But where paint cabinets provide the right colors, here you have to manage with what we have at home, that is often the children crayons. But the proposed designs require 3 or 4 shades of brown, 3 or 4 shades of green ... Besides if we have professional equipment, I do not see how you can do! Then, good ideas coloring areas is confounded by the fact that the same color is repeated on neighboring areas, creating the final large applats of the same color. Instead of meticulous coloring (it is sometimes the case), we are left with roughly sweep large areas to finish faster. Too bad! One adult for coloring could be more specific, more demanding. The few drawings point to point are nice but again not quite complex. We guess too far in advance the final design, and there are not enough points.
