I'll just reiterate what Simon said.
It looks like you just need to align the strings by adjusting the lateral neck angle.
If you measure the distance from your centre mark at the neck pocket to the centre of each E string in your photo, they look pretty equal to me.
This is one of the beauties of screw-fixed necks vs set necks, they're adjustable!

If you haven't drill the holes in the heel yet, you're laughing. Set the correct string alignment first, snug up your clamp and mark the hole locations via the holes in the body.
Once you screw the neck on, you be able to realign the strings easy peasy.
