colour looks great Slayer, can you please post some close up pics of the glue affected areas ? Might be worth getting a small wire brush before you go any further. Also mark the neck pocket where it meets the body. Try keep stain off the neck pocket that will be glued to the pocket.
You dig the new Metallica album Hardwired ?
EDIT as Fretty said I recommend shaping your headstock, even a curve would look cool.
