Dragon beneath the river

The Birth of a dragon. Its legend that the Koi fish will become a dragon, hence the dragon beneath water and Koi, shows the evolution, beginning and after the destiny of the koi fish. this took about 10 hours in total, done in water paints (originaly in colour) on A3 size paper. Once again I couldnt decide what I prefered better, the colour version or the black and white, what do you guys think is best?
