Is my PCB wiring correct?

[Sashvat]

Hi guys, I have made a MC dev board out of an STM32F33K4T6 and I wanted to know if my PCB wiring is fine. The trace width I have used for this is 0.254mm. I shared another post of the same question, but for some reason, the server is down and I am not able to see the question nor able to reply to it. Please let me know if this board will power on and will I be able to run programs on it? I have attached the schematic and my PCB, I will fill the ground copper area on both top and bottom, but so that you check and verify it, I thought Ill remove it and share it with you.

Thank you
