It's a juniper, you need to leave lots of green, when you prune, or it will die. Junipers are among the "newbie" trees, but, there's a few things you can't do to them:
1)Keep them inside (they need to be out in the sun)
2)Over water (they like it dry)
3)Prune off the green (they don't back bud well)
Maybe, there's a bonsai club close by.
be patient, let it grow while you learn. I can't see anything to cut, perhaps if you found someone that can touch it, they might be of help.
