I did a trial run on your GCode and the results are not good.
Your design lends itself better to acid etch than it does to routing mainly because of the fineness of the tracks. The loading which mechanical cutting puts on the copper substrate can approach the bond strength between the copper and the board when such fine tracks are milled and as can be seen from the photo part of the tracks are missing.
If you thicken up the traces, you may be in with a chance but, as it stands, this design would be extremely difficult to produce with a router.
