I did a small study of three orchid flowers.I like the small one in the left corner the most. In real life I like vandas (the big purple one) really much, but they are not so great to paint. The pattern! It almost drove me crazy.You use only one color, but have to follow the pattern of the flower to make it really look like a vanda.
I had some problems with the pink. Somehow I'm almost never happy with the way the pink turns out when the paper is dry. Maybe I have to buy more pink paint from different brands.
