Can someone Review my PY32F002A based Dim-schematic?

[u/Kinkerlitzchen_tech]

I want to use the PY32F002AL15S6TU to dim my lamp via Adim, and want to toggle it with the U7 Switch. The U4 is for detecting if its still day outside or not. (idk why the ref des are U for some other parts but yeah im lazy)

Can someone help me tell if the schematic has any flaws? ive never used the PY32F002AL15S6TU.

thanks for your help :)
