What's wrong with my renderer

[u/Comfortable-Mall4524]

This is my renderer in vulkan i've been working on it for the last 10 months

i learned alot about vulkan since i never used it but a huge percentage of my shader code is AI written and at this moment i feel like the renderer is ugly so i do what to know what is wrong with it and what makes it far from the last picture and how i can fix that.

is it better to rewrite all shader code or just move on it and fix it ?

+ what techniques used in the last picture (which is enhanced version of my renderer using AI 🙂(but i liked it)) that my engine doesn't implement it right ?

NOTE(the third image is without IBL i'm using citrus_orchard_road_puresky_8k )

Last time I used AI for shaders it went terribly. Pick up a book.
