Waterlily No.2 by Alvin Phua

This painting caught my eye. it is crisp, has form and the tones are great in my humble opinion! each petal is so well defined . it is such an accurate interpretation. i like it very much. sara

I like the crispness of the flower and it's subtle colouring. Perhaps consider portraying just the flower, no stems no leaves on a graduated-toned background (as you have here). How big is it? What medium?
