Size matters

As I was sorting through some resent shots,  I started to think about what made one similar shot better than another.  Both images present the viewer with a single point of interest on a blank background, in fact they are the same subject.  So what are the defining differences?  If we ignore for the moment the difference of shading of the background, I accredit the main difference to be the size of the subject relative to the ground.  The first image gives a greater sense of  scale while the second is a more direct representation, here is a lady bird beetle no more no less.
