The one on the left looks like an armored Fire Giant. The other maybe a Frost Giant or a well dressed Hill Giant. Maybe the Frost Giant was visiting his best friend from primary Giant school and some adventurers showed up. I think in the game it would be nice to have random personality trait charts like a GM Emulator or NPC Emulator that gives us traits or characteristics like 'collector', 'rude', 'polite', 'educated', 'uneducated', 'brutish', 'seeks non-violent solutions' to give the GM little hooks to their creation and play of that npc that result in memorable and potentially unique giants, giving them more texture and life. Me, Myself and Die used charts like that, and Giants and other creatures are a big feature so why not at least one Personality Trait/NPC Characteristic chart for each type. Look at NPC Emulators and others. This might be a most satisfying feature. If it doesn't fit in the book, this is a great stretch goal for the stretch goal book or 'free' download after the campaign for those who buy the book, again if it doesn't fit. The GM will discover along with the players things he or she won't know or guess until the Dice determine the texture of a given Giant or other npc. Key npc's and unique named npcs can be defined so this is for all the rest of them.
