I really love the colouring and the shape of the fractal. You have requested critique, I'll try to do my best. Thenly thing I want to mention is the lower area of the picture. The lines there are interesting, it seems like a spider web, but I get the impression that it is, uhm, what to say, unfinished and together with the rhombus shapes in the petals of the flower it may seem a little bit messy. Maybe you can zoom the fractal a bit more, make it fill more of the space. But it is only my opinion. It is really a nice work.
