General comments
Values for R8 and R9 are very unusual, you probably want to find more common values (e.g. E6 resistors)
Sensors J1, J2 - probably needs to explain what kind of sensor goes on there. It's also not absolutely clear why R1 exists (current limit I guess)
LED resistors (R5,R6) - the LEDs might be uncomfortably bright / have short life as they will be running close to their rated current, consider 1.5k for a still visible indicator with better longevity. Obviously this depends what LEDs you use and other things (such as if the device is intended for outdoor use).
You might want a comment on the range of VDC, and note what voltage ratings the various capacitors need (if VDC is much greater than 5V)
Capacitor C3 it is unclear why this needs to be an electrolytic, you might be able to use a ceramic. 16uF is an unusual value looks like it's come out of a calculator / automated design tool, consider putting a more standard value (e.g. 22uf)
