An average picture of a nice butterfly. Not world class commercial quality, which is what you need for stock.
Thanks for sharing. Try to focus better next time. Maybe a higher f/stop.
I believe it may be a male hypolimnas misippus. The females are much more colourful.
You are a butterfly expert? 😄
Sorry, but I think that your phone does not take macro pictures with a quality required for stock. Phone pictures in general are a problem, as their small sensor and lenses have limitations that make it difficult to get high-quality pictures. This said, it is possible to submit successfully phone pictures.
