"P-goop" is the Polaroid processing gel inside the little pod - the quasi-caustic goop you try to keep off your fingers when you peel the Polaroid apart.
I suggest getting in a little closer, to emphasize the lighter flower, and make the image a touch more abstract, rather then representational. Perhaps because the subject is so nice, we don't want to exclude any of it, but that can result in a slight feeling of distance from the subject.
I don't know where on this forum we can post other images, so I posted it here: http://www.kenleegallery.com/ralph.html
I have also taken the liberty of making a 4x10 image from the same photo - a little more abstract, kind of like a Japanese or Chinese painting. See http://www.kenleegallery.com/ralph2.html
I hope this kind of "critique" is OK, and not offensive.
