If I had to use your bracket, I would try mounting the ballhead/speedlight under the top bracket connect. It is too far away from your subject, and pointed incorrectly (light will not bend in your diffuser, no matter how you angle the diffuser face). With your 65-mm lens at 1:1 magnification, your subject is about 4-inches in front of your lens. At 2:1 mag, even closer.
Thanks Douglass, Ive ordered myself a diffuser and will try re-configuring the bracket/flash setup. Much appreciated
