OK, you're just outta your mind in general. ;) Actually, I think it looks very real. The flowers DO have sharp edges, which can be seen considering the way they all contrast (very nicely, I might add) with their individual backgrounds. How sharp of an edge could you hope to put on a flower anyway, especially when the edge is a solid color? Flower petals tend to be very thin things and if the geometry of a flower model is proportionally thin, as compared to its' surroundings, I would thimk it would be giving a fairly realistic edge, no matter what. Unless the render program isn't doing it's job right, in which case....well, you know. ;) Otherwise, I have no suggestons, but maybe some masking in PS with some sharpening of the selection? Hell if I know, and I think it looks great as it is.
