Wow, it's so beautiful and detailed, I can't understand why the comment section isn't flooded with compliments!
I love the mix of ink and watercolours, it creates an outcome that is both strong and delicate at the same time.
The composition is lovely: the butterflies look a bit like the flowers so there is this sense of continuity. The colours you chose are very beautiful and while there are many of them, they all match and are not distracting at all. Lovely work!
