Image Description: Unfinished prototype next to a partially assembled Marine of standard height and similar pose. Gives an idea of the subtle height difference but the considerable difference in its appearance in regards to bulk and grimdarkiness. I think the additional ammunition, grenades, pistol, and combat blade give him a much more threatening feel as befits a Space Marine.
Love your blog. Dont like having a marine with busted arm, even if it 'just happened'. Wrist auspex is brilliant as is the pouches/grenades on front harness - now my own marines look small and like light infantry! Superb work on postures, you are right the normal arms give a weap pose, either pointing at the ground or on a 'gangsta' angle no professional soldier would ever use.
