I excluded the horns from the side view as they'd make it hard to see the side of the Giant's face while modelling, and the black diamond on his torso is to indicate where the arms start.

Let me know what you think!

These faces are mostly a mixture of previous sketches  to create something more interesting and closer to finalised. At the moment, I'm mostly liking the look of 2, but I'll take a few of these faces into Photoshop to neaten everything up, start working on colour, and make any necessary changes.

With these sketches, I was trying to discern what male/female variants of the creature would look like, as well as how their foliage should look. At the moment, I'm liking the look of branches protruding from some of their joints (especially around the torso) and their heads.

I'll continue trying out different shapes of leaves for their foliage but think that keeping everything small and spindly looks the best, at least for smaller creatures. Perhaps larger leaves would look better on the quadruped?

I'm liking the look of 1 and 13, so I'll most likely recreate those designs in Photoshop and make some variations of them, and make them look a little more rigid and skinny, as well as slightly alter the overall pose of 13, especially the arms. On top of exploring more in terms of overall design, I want to experiment more with their faces, as I think it would be interesting if they wore some kind of masks or decorated themselves in some way, perhaps actually carving their faces into the shape of masks as they're made of wood.

Although the metal arm would possibly make the character more recognisable as Furiosa, I'm leaning more towards #2 as she is missing her arm in the scene I will be replicating.
