Aww aww aww the colors! Yumm, that looks good. The array of colors and the general toning of this image is just amazing - one of the best colorschemes and artist can go for, in my opinion . Next thing, also very good, the intergration of brushing/2d and the render itself: perfectly integrated - the eye is almost unable to discern two layers in this piece, which is a real pro.
Some negative parts of this image: Where the render gets cluttered, jags appear and tend to ruin the smooth and flowing look of the image. The rest is perfect, worth a fave. Great job you both, shows what happens when two good dutch people get together .
