Elizabethan Styles & Padding

Ive found in my research that a lot of elizabethan styles, most noticeably worn by Queen Elizabeth herself, feature great volume and structure often creating through the use of 'frizzing' and manipulating around various types of padding of metal frames to support the hair in to extravagant shapes.
Take for example The Armada Portrait c.1588.

In this portrait the hair has been frizzed and pulled firmly in to a symmetrical shape around the head. The shape is typical to that of what Ive already seen throughout my research, two symmetrical domes forming a subtle heart shape. the hair would have been frizzed and manoeuvred over some sort of padding or structure to achieve this look.

In my practical session I have tried to emulate this technique to use in my own designs.
1. I began by sectioning and crimping all of the hair.

 2. I then sectioned enough hair at the front of the head to cover my padding and clipped out of the way.
3. I then created a french plait directly underneath this section would would act as a base for my padding

4. Using Bobby pins I secured the padded tights on to the plait.

5. Starting with the bottom section of hair first, I pulled the hair around the padding securing in place with pins
6. I then repeated this step with the front section of hair, making sure to hide the pins as strategically as possible

Here is the finished look from the front. I'm quite pleased with how well I've covered the padding, as none could be seen. However I didn't manage to get the shape i had envisaged, i wanted the two shapes to be more prominent on top of the head, whereas in the image they are more to the side.
