Turn the wheel so the valve is a the 6 o'clock position. Stand to the side of the bike (does not matter which side) and look down at the valve. The first spoke to the left of the valve should go to the flange on the other side.(away from you) If this is not the case, as I suspect looking at what I can see of your photos, it was laced incorrectly.
This rule is nearly universal although I have seen rare exceptions. CR 18 rims would certainly not be an exception to this rule.
