It's created in a fractal program and fractals are part of it's beauty so you could say the fractal gallery...but Remember the focal point story from a while ago,what's the focal point here?At first you are tempted to say the flowers but for someone else it might be the fractal swirls around the flowers.Is keith as the creator allowed to decide what the focal point is or are we who did not create it decide that for him? I would say let the creator decide that,Mixed medium or fractal gallery both are ok in this case.
