The proportions on Craig's head feel really solid, especially around the tusks and the width of the skull. Elephants are deceptively tricky to draw because the masses don't read the way you expect them to at first. I've done a few studies trying to get their leg construction right and it humbled me fast. This has a nice weight to it.

The weight in that trunk reads so clearly. Graphite's unforgiving when it comes to elephants, every plane has to sit right or the whole form collapses, and you nailed the structure here.
