On this picture, notice the indention made in his pelvic region? I'm a little confused on if that is made my the pelvis, or the muscles over it or just some people have it, some don't (if so, how is it placed?) Upon drawing a pelvis, I was trying to see where that indention is made and couldn't figure it out T_T. Help CA!
If a link provided to someplace that can describe this to me, it would be great help, unless you can explain it better .
