It took me a long time to create a simulation of earth like that. I wanted to show the real spinning speed of earth. Here's my video:
From this NASA live stream, I can visually notice that the earth spins a little bit faster than my simulation:
Why is that? Is it because of the Zoom out or the scale down of earth in my video? Is it because of the movement of the space station? Is it something wrong with the simulation?

I'd suggest for your next project, to make a satellite in a geosynchronous orbit in real time. So you'd have to animate night time, the Sun, and city lights. It might be a lot for a computer to render.

In your simulation, the camera (or the viewers perspective) is stationary in what seems like in an altitude of a geostationary orbit. However the ISS is not stationary, it is travelling 7.6 km/s. It completes one orbit in 92 minutes. The ISS orbiting is giving the illusion that the Earth is spinning that fast.
Note: The Earth does still spin while the ISS is orbiting (obviously) but it doesn't spin as fast as you think it does in the second video.
So in summary, in the video below your simulation, that is not the Earth spinning, it's the ISS orbiting the Earth. Your simulation is correct and you could add clouds to make it look even better :)

The ISS takes approximately 90 minutes to circle the Earth. This presumably results in the higher apparent speed of rotation.
