Nice project! Just a few things - first of all, could you please upload your gerber and drill files as one zip to your PCB folder? Secondly, could you please share an image of all of the components assembled (including 3d models of your XIAO and switches) from the top view? Finally, your text seems to be on the wrong layer. MAKE SURE IT IS ON THE SILKSCREEN LAYER (beige, not yellow) or it won't appear and might break your PCB!
