Tree looks nice and healthy. Sometimes brown tips can be a result of physical damage; either you brushed against it the wrong way or mishandled it during wiring, or any one of numerous other physical causes. Regardless, the damage does not look worrisome to me.
As far as hard needle foliage, what you are seeing is what I described earlier. Procumbens junipers (and most other junipers) have two types of foliage. Juvenile foliage is prickly needle, and adult foliage is softer scale (without needles). As seedling, all the foliage is needle foliage, and as the tree gets larger, the tendency is to change over to adult scale foliage. However some actions can trigger an adult tree to revert from adult foliage back to partial (or almost complete) needle foliage - like heavy pruning, heavy fertilization, or repotting. Usually once the tree recovers from whatever triggered the spurt of juvenile growth it will shift back to adult scale foliage.
There are some junipers, known generally as "needle junipers" that maintain juvenile needle growth always. Other junipers, like Chinese junipers (and specifically shimpaku Chinese junipers) are prized for bonsai because they maintain scale foliage and only rarely throw needle foliage - even after heavy pruning. Procumbens is right in the middle.
