Blurry Fuzz with flash

[bes]

I'm hoping someone may point me in the right direction, I take few pictures and 99% of them are bad... out of focus, out of shot, massively over blown , I'm guessing the usual noobie macro mistakes. On the rare occasion I do get something roughly in focus I sometimes get this fuzzy ghosting happening on the edges.

I use a 1100d with an old pentax 28-70mm lens. I hold the camera in one hand while holding a flash with diffuser in the other. This pic the shutter was 1/128sec and iso400 and maybe f5.6ish fstop. The diffused flash was set to 1/8 power. What is this fuzz and how do I stop it?
