Interesting designs.
Use of trees and stone is good, but needs more glass and wood, and more distinction between trunk/plank.

Otherwise, looks nice so far. Good job.

What, do you expect us to sleep in the trees? Leave that to the squirrels. I prefer to have my boots on the ground, or be inside the earth where myself and other dwarves belong. And as for the library, any young dwarf with a pick can get through those pistons! No meat?! Does that mean that even if we bring our own, we can't eat? I don't know about the other, but I'd get tired of bread and fruit quite fast. And as for a shrub house, am I a rabbit, or am I a dwarf? You elves were always so obsessed with finesse, and beauty. The most beautiful things I've ever seen were made of Iron and Gold, and never saw the light of a day.
There. Conflict between the Elves and the Dwarves has been set. Now, to get MC full.

We respect the animals we have tamed. Cavern dragons, Mountain Wolves, Stone Golems, and the fearsome Volcanic Beasts. Our tunnels are their homes, our wars are their wars. Our villages are fortified with the stone, and bedrock, and iron that we work so hard to achieve. You elves think yourselves so mighty. How do you expect to survive any attacks? With those two, flimsy Iron Golems? We do not wage war. we perfect it. Even a small group of Dwarves could easily take your village. Then what will you do? Our guns will destroy you, your bones will be ground to dust beneath booted heel. Renounce your laws, change your village. The waste of any lives would be tragic.

I have seen a mod somewhere that adds guns to the MC.

We have the acquired skill of millenia of combat. You have a few trees, arrows, and a bit of finesse. We to harness the energy of the earth, and use it in our cannons. gunpowder, coal, iron, and lava. We will set your village alight, and kill all who flee. We do not need finesse. Only accuracy. For one hit from our hammers, or a superior dwarvish sword, and you are short an Elf. Your arrows can fly far. Our rounds can fly farther. We will tunnel beneath the Aerasume and destroy all that you have worked for with out TNT. What will you do then? Hide in your temple?

You're bold, Elf, I'll give ya that. Will you face our fortresses, and delve deeper than any outside of the Dwarves, or the Immortal's Guardians. The dragons will be torn from the skies, the trees will be set alight by our flamers, your "friends" will be cut down by the hundreds, and cooked to feed our armies. Will you condemn so many races to extinction simply for pride? You are arrogant, and overconfident, elven witch. And bear in mind, even Sarcof will not step between this conflict, unless he has excellent cause. We will capture your village and remake it in Iron and Gold.

Now pronounce that. Good luck, Elf. Even your armies cannot win. You will smash against the anvil of our Holds, while the hammer of our warriors beat you into oblivion like the stone that we mine.

Prepare to face extinction.

Bloody elves.

Shame.
