It was time to finish up, which meant actually knowing what the gate was saying. After some research, I learned it was Chinese.
I used that info to recreate the (mostly) correct wording.
I also did final polish, like fixing some texture tiling, improving the geo on the stairs and adding grunge to the signs.
The tree trunk was as an eye sore, so I used some foliage to hide it.
The cliff wall on the left blocked out the light and helped frame the scene better, as the stairs lead your eyes from the bottom, through the gate and to the light.
Finally, a post processing volume, which added some much needed color tweaking, contrast and ambient occlusion.
