Yesterday I put a sculpting chart up as a resource for folks to use, but after some good points from a friend (cheers Migs!) I've decided to scrap it and start again.
Looking again with fresh eyes, the proportions for the marines and humans don't scale 1:1 at all sizes - some creative modification is required in order to produce sculpts that both look realistic, yet also allow room for detail and characterisation.
Therefore I intend to rework these from scratch for each scale - it'll take a bit longer but hopefully be worth the effort.
