Hi Guys, a year ago a friend from a nursery gave a juniper that was kind of sick. After give the tree some TLC finally I found that it was the time to practice on him. I say practice because I don't have a real experience doing bonsai's. My techniques aren't the great so my apologizes to those "master's" in the forum. What Im asking today is help regarding the shape of the tree. I don't know if I did too much or what could I do to have a better tree and lastly what should I do for winter care (Zipcode 14620)? I usually leave my others bonsai's (jap boxwood, elm) on a unheated sunroom, should I include my new bonsai on this room for the winter?

Thanks for you help in advance. Here at the links for the pics
