Heath really looks like shit proportionally. His head is literally takes up the space between his shoulders. Both his pecs combined are "1 Heath head wide". 
Finally somebody aknowledges the subject of proportion.
Heaths is a limb guy, he has big arms and legs but his torso is small making his back shots smaller and his chest is just bad all over.
Chest and arms are the most important things to have IMO.
And to judges it's back, but heaths back lack in rls because of width and proportion. However his rdb is very good. But that is basically his only great pose.
