The execution is fantastically detailed and consistent, and the contrasts between shades and highlights make the mini easy to "read". I like the bold color choices, too, although strong blue _and_ green _and_ red are quite a lot.
What I don't like so much is the range of colors you used to highlight the green fabric and the skin. I know that green is very hard to highlight (do you go to warm yellow lights, or to cold whitish ones...), but somehow it feels like the highlight areas are not only lighter but also of a different color altogether. For example, the green looks like it is worn out and bleached in the yellow areas.
