A few days before I delivered baby Nawang, I made a colour test of the black orchids (Coelogyne pandurata) from Borneo, whose flowers blossomed less than 5 days. It has no flower anymore but the colour test will help me to paint the illustration later. I already made the sketch while it bloomed and took some photographs of it.
green petals were quite simple, whereas the black lips were the real
challenge! And I am afraid I can't capture its intricacy well in the
real life size illustration :p
