looking good Sandman, think the level of black ink left in the cap is fine and will look great stained. Doesn't really matter what colour you choose these flame maple tops will look excellent. I'd probably stain the veneer first then decide the colour for back/sides of the body and neck, it may turn out slightly different to your original planned colour.
I think you will find black hardware and pup surrounds will go better with the dark flames
good luck !
