Try to expand the SIDE ball texture until align it.

I say, like.. Select it, and try to expand the altitude only, ignore the latitude.

Well details on the torso parts are forgiveable to not being too detailed, I mean focusing on the most visible parts should do it.

And yeah, as someone said on the first page of this thread, The head lacks more details, specially on back-side, and I do like the theme of the set, I don't know if I catched this theme right, but I think as far as what is already drawn there, it's pretty much suited every available part of the set.

Difficult to explain, but if you duplicate your texture, then squash and rotate each bar to line up with the pec piece on the template, you'll see the exact lines you need.
