A little disappointed ... very childish coloring

I was very disappointed with this one because I find them too childish drawings with large parts coloring. So I otherwise use, mixing coloring and collage on the larger parts, for example, a skirt a bit too large and without detail, I add the ground a little piece of fabric or tapestry or even some sequins, ribbons or colored adhesive ...

I think this album would be ideal for a child or teenager.
