Look at the crown on this tree. It could be the photograph but it is impossible to see the branching other than some of the primaries.I've done it a time or two, the dark brown layer is real thin, the bark underneath is a nice rusty brown like other junipers, it is just a lot of trouble when you start working around the branches. Not sure what you mean about being overgrown, if pruned properly they seem to look as good as any of the other species.
