building web crane

I am converting a toy crane to a web crane. I have to control 3 DC motors and a magnet.

End positions will be detected using photo interruptors.

I took a lot of time doing the circuit picture above. All the other circuits I did so far I just rebuilt what I had on the breadboard, not using any schematics.
I wonder if its worth documenting it like that?

next I will have to find a good magnet to lift stuff, build a switches to detect when the hook is up and down
write the server and the client side software
