When it comes to plot, all the planning and political manuveuring can be somewhat difficult to follow, but luckily most of the schemes are explained in detail at the end of the arc, much like what is done in mystery/detective stories, so we can easily understand everything that is happening. In terms of plot progression, the plot is moving along nicely. Season 1 was mostly an introduction to the main players in the Tian Xing Jiu Ge (Qin's Moon prequel). While there was a buch of stuff happening there, there were no major moves or stakes until the very end of the season. In this season, we now have some major moves politically and by the end, we can see that a greater conflict is about to begin, while most of it was previously contained in the Han Kingdom (the main stage for this story so far).
This season is much newer, having been released in 2020, so the models, rendering, everything is updated. They look much better than season 1 which was released starting in 2016. The animations are much smoother, the models are much cleaner, and the fights are have much better choreography and flow.
The only thing of note is that this is clearly half a season, as season 1 was 60 episodes and episode 90 clearly has a next episode preview.
