Common juniper is the common name for juniperus communis. This is not a communis.
As far as I understand, for good pads you spread/fan out the foliage as you did in the last picture. Try to make it flat and even for every horizontal layer. Eventually, the growth will go upwards and form pads. But since you're dealing with juvenile foliage, there's no saying on how long that would take.
You wired some branches upwards, that means that eventually, the branches originating from there will need to be wired flat again. Unless they're the apex.
There are some good juniper video's out there. Right now you've set the structure for pads to form somewhat like this (but since foliage grows outwards, they might end up shifted to the direction they're growing in):

If this is your chosen front, then there's an issue on the right hand side; you have to pads in each others way. Eventually one will have to go.
But working without a defined front will make things hard for you to style. I would personally even say that this tree isn't ready for styling yet because it's producing juvenile foliage only.
If this is a procumbens juniper, then you might want to tighten up the foliage first by pruning effectively during the growing season. But I don't know what kind of juniper we're talking about here.
