Those flowers (especially the pink lilies - I think that's what they are) look so realistic! This piece reminds me of the wonderful paintings created by the very talented Malaysian artist Limzy (https://www.instagram.com/lovelimzy/?hl=en).

I too believe that Nature is Art - which is why I love using flower petals for my origami creations and that you can't beat nature for the finest materials and inspirations for art!
