The color and arching growth habit reminds me of a Tam juniper, maybe? Regardless, I agree with Shibui's advice to style it slowly, especially if you don't know what you want to do. Start with one or two branches you know you absolutely don't like or feel are way out of proportion and shorten them. Then look at the tree again for a few days (or weeks) and see if anything else stands out that you don't like and reduce or remove that next. When I don't know what to do with a piece, I approach it slowly like this. It's sort of an extension of the axiom, "If you don't know where the front of your tree should be, find the back. Your front's gotta be on the other side." And doing a little work at a time is less stressful for the juniper too.
For certain, reduce any junctions with multiple branches down to just two, so those spots don't get thick and produce ugly inverse taper on your trunk. If you have a lot of long, leggy growth, then maybe start with slowly pushing it back at the tips to encourage backbudding on the interior. Just don't remove all the heatlhy green foliage from a branch you want because it will die. Reduce, wait for it to backbud, then when that growth is strong, reduce some more.... Good luck and have fun with it. Sometimes you've just got to jump in and try things. I butchered several cheap nana junipers before I started to get some feel for designing them. Still learning.
