Validate design of a simple electronic circuit

Description

This request is for a design validation of a simple (micro)electronic circuit with a 9V battery source.The circuit/project includes the following components:- NE555 Timer DIP8- capacitors- resistors- potentiometer- LEDs- speakerThe project has been implemented and works on a 'breadboard' platform.I need to have these two things validated:a) validate my conversion of the 'breadboard' implementation to KiCad schematicsb) if needed, validate the KiCad PCB Layout based on the KiCad schenaticsBreadboard layout/description and both KiCad images/versions are available. Photos and videos demonstrating the functionality of the breadboard design are also available.
