I've been thinking around the whole knotty problem of Treebeard and the Ents (especially the Entwives) for a good while now and am still at the drawing stage, trying to work out what they actually look like. As Treebeard says, let's not be hasty. Tolkien's descriptions really don't help, creating additional problems like how does Treebeard's head work when there doesn't appear to be a neck as such? How do you stop Treebeard's barky 'trunk' with smooth arms from looking like he's striding about wearing an all weather gilet? And how do you make female ents look... well... female when they also must have rough barky skin and 'treeish' proportions.
I've only got as far as Treebeard's head - the rest of his body is still an unknown country - and he has come out very twiggy with peeling bark and lichen eyebrows, owl-like eyes and a circular, knotty effect that looks very satisfyingly like wrinkles and wierd facial tatoos all in one go:
The Entwives gave me a lot of problems. They need to be plainly female but if you make them too barky you can't refine their features and they look rather male, if you make them smooth they look rather naked. I've given them some strategically placed peeling bark that leaves most of their heads and faces clear. Here is a sketch for a Fimbrethil painting. She appears as Treebeard would have last seen her, bent and rosy cheeked, and if it was in colour you'd see the straw like, bleached colour of her hair:
It's not a final version and I've done some more Entwives since which shows them evolving a little so I expect she'll end up looking quite different when I get around to painting her! I have tall thin Entwives and a fat, jolly Entwife. I guess, like Ents and people, they come in all shapes, sizes and personalities. I think the bottom one looks as though she might be rather hasty, given half a chance:
