I made a quick design for a circuit board now that the circuit itself seems to be in place

The only detail im somewhat worried about is the connection from pin 4 of the 555 to VCC, I couldnt get around easily so what I did is I managed to connect it to the cathode of the third diode (parallel to the motor) which goes to VCC as well. Please let me know if that is a huge mistake I know the design isnt the best but it was a bit of a rushed job and for know I just trying not to blow it up.

If you see any other mistakes please let me know, Ive attached the screencap

Thanks

Could you post the diptrace design file? you may have to put it in a zip file first to post to the forum though.
