*inhales deeply*
you need to draw from life. a lot.
That doesn't look like a real flower.
This is a flower. Your drawing is an idea of a flower. It's what you simplify a flower to being, not what it actually is. To stylize correctly, you have to know what actual flowers look like, for example
this is a drawing of a lotus flower that is stylized. You can still tell it's a lotus flower because the shape is right, and the important details are still there.
tl;dr: draw from life, then stylize.
