Nice tree. I like it as starter material. Nice choice. Think about what future you see for this juniper. I suggest pondering for at least 3 to 6 months, or longer before beginning to style this tree.
I like the amount of movement in all your branches, and the branches are no young wispy branches, these branches have some wood. For this reason I would do my best to come up with a design that used all your existing branches. I would try to come up with a design that cut off zero, or at most one branch. I would like to see you keep them all.
Your photos are all of the same side of the tree. Before planning a style, take a look at this tree, and photograph it from 4 or 8 sides.
4 sides, rotated 90 degrees,
or
8 sides, rotated 45 degrees.
Just seeing it in photos from all 8 sides 45 degrees apart, may give you better ideas for a front, and a design.
In general, in part to create the illusion of height, most bonsai the trunk tilts or leans toward the viewer. The photos you show all the branches are moving away from the viewer, I really think your possible front is what is the back side of the tree from the 2 photos you posted. This is common in bonsai design. Front & back are related and often can be interchanged. But the "leaning toward the viewer" is a key feature to keep in mind. Though this can be corrected by repotting and changing the angle the tree inserts into the soil.
So my advice would be cut nothing. Take your time to contemplate several options for a while. I often keep a tree on my bench a year or more before styling. Contemplating designs during the time I take to get to "know" a tree.
Make drawings, take photos and do photoshop, paint or other editing tools on the photos.
This is a nice enough juniper that I would like to see you go slow, rather than rush.
