I find albino skin often has a very pinkish undertone. If you're looking to define the scales, you might want to try a Baal Red wash and brush some white back over that for highlights. Do a test area first, though. It could be very bright.
If pink isn't your thing, albino pythons are a bit of a yellowy-beige colour, and still retain a lot of their pattern. Maybe look up some images of other albino lizards to see what you could do to make the scales stand out a bit more?
Or leave it the way it is if you like it, of course =P
