I would agree with Denny re the border if just to separate it from the white background. I like flowers too (Denny) and this is a lovely example, can almost smell it! One thing to watch out for is for burning out the edges of petals on light coloured blooms - you are OK here but there is not much margin for error.

Cheers, Peter.
