advanced delay circuit

In short, works fine, looks great and everyone I show this to is impressed. I was expecting the serial number to be as big as I made the "WayWayWay" area on silk layer. This circuit powers a 24vdc sensor and 3.3vdc microcontroller, and outputs a signal at 24vdc for solenoid. Micro controller Is programmed with a special delay regulated by two potentiometers. I like how compact the mother boar is and cant imagine the outcome it I used smd components. I dont have experience soldering smd that's way I used THT component's. For next time I would increase the pad size for the transformer, because its a heavy component. I know I dont have filters and dont comply with eu standards but I enjoy making stuff that works and lasts. Thank you for my first PCB.
