Modelling a!

Hi Guys,
I need some help. I have been trying to model a badge from a supplied Illustrator drawing.
I am trying to make the basic form and then project the curves onto the surface and then boolean shapes out of it.
I have redrawn the outline and have tried to extrude and fillet which doesn’t work. I have tried rail revolve which was better but still no good. I have tried mesh and then Subd but I haven’t used it enough to really know what to do.
The spiky leaves around the outline have been a real pain and I am thinking smoothing the curve to give myself a fighting chance.
I’m also interested to see if there is a way to do this as is.
If anyone can help I would be very grateful.

I smoothed off the outline and created the initial shape.
A bunch of work to do but I think I have a way forward.
