You need to know the reason for 'diffusion dome' or diffuser
Its basically kill some flash power, so that it goes into all direction.

There is two main factors to softness of light. #1 Light source surface (flash is about 3cm x 6cm, adding the dome... it may give you 3.5cmx 6.5cm. That's why the effect of dome is minimal as its best. But hey, it at least kills you one stop to 1/2 stop of light and may be gives you the "pro" look.)
#2. distance between light and subject... the closer the softer. And in this case, it may cut you down... like 1cm?

The actual useful for dome is when you bound it to ceiling or wall, you can "add" some, a little bit of on-axis fill light.
