I would like to suggest some things

[bard]
For the bard, only 6 mussics is a really low ammount. So i would suggest either adding more songs or letting people use a custom song id for the bard.

[torque shafts]

The torque shafts are quite hard to understand how they work, which makes it almost impossible to connect the torqueshafts to a machine and a power source at least for people like me who don't understand about this stuff. What i would suggest is adding an simplified way of putting down torque shafts. For that, it would've good that whit the hammer you could only connect / disconnect a shaft from another type of shaft. That would make things way easier and it would require of just hitting from above the places where you want, for example, your torque shaft to be connect to your torque junction.

[buildings]

There are quite loads of pre made buildings. But there should've more. Like, from different ages and not just medieval. I know we are talking about ancient stuff. But the description of the mod clearely says "you can either build a kingdom or a city". So it would've really cool to have new types of buildings which are of the modern age and maybe some cables or something more modern to match the style

[npcs]

The last suggestion would've to add more types of npcs. Like, for making a modern city, it would've cool if you could have soldiers which can be equipped whit guns from other mods. Or also some workers which can use vehicles from other mods. Like a harvester or a car.

And that's everything i would suggest
