Heh, that was the fanservice post haha!
Guntur looks gorgeous! I definitely approve of the changes!
As for Kahlil, I think you don't have to define the muscles as much as in the second version. But if you want him to still look a bit more lean, I'd suggest you to go for the base of the first version, but do the belly and hips region more like on the second one, maybe in that same zone, start outlining the abs but only the overall outline of all the abs, not each individual muscle. From where I stand, his belly looks okay in the second pic, but the more you go near the pecs, the more it's too much muscle? That's why I suggested that. Does it make sense? I'm not even sure XD
