The hard part is that what is involved in helping you amounts to a Bonsai 101 & Design 101. Much easier to have a conversation about than it is to type... cuz believe me, it would be a lot of typing. Hence why people ask you to seek out local experts.
Read this post on helpfulgardener.com... I once was trying to help out some newer learners on another forum... it might help with some of your more basic questions.

In this next thread we got into a discussion about design concepts...

This last thread had very useful conversation in general which you might find helpful...

The most basic problem with the tree at the moment is that the foliage is very long and linear, the lower branches are tightly spaced together where they will eventually swell and distort the shape of the tree if they are all left as they are, and it's a fairly smallish tree. For the mass of the trunk, your crown shape would be closer to the trunk where you don't have as much foliage because it's all out on the long sections which you don't want/need. So your job is to learn horticulture first... design concepts second. Dont worry about designing this tree... learn how to make it respond to you by chasing that foliage back closer to the trunk. Because it's a juniper it'll tend to want to sprout new growth most strongly from the crotches of the branches. Constant feeding in the growning season will create fantastic results for growth and back-budding. But in the end - like early next summer - branches must be selected and significantly shortened with a heavy feeding schedule to get foliage where you need it... but not now... right now keep it happy... and work on chasing back that foliage.
THEN... you can work on adding interesting movement to branches. I rarely work a tree I haven't had for 3-4 seasons... I get it to optimal health, and then work on design. But i have lots of trees... so giving them time causes me no pain.
