Oh my goodness, never really commented on someone else's nice photo before but here goes... Just my thoughts, since you ask.
Like you say the background looks like brush strokes, really nice. I think it needs cropping more at the left, there is very little interest at the left, although I think the subject needs plenty of space in this image. The head (eye?) seems dead centre, too symmetrical . The yellow flower is fine, I hadn't noticed it until I read your text. There is nice reflection and ripples, like you say it's different from dead calm mirror smooth reflections, although they can be spectacular.
Just my two cents.
