I really like the colors you picked for your AoW Saurus. It's looking very good! The only thing I would add is a little contrast on the scales. They look exactly like the skin.
Yeah I get it that he is an albino but a little contrast wouldn't hurt. For instance, you could use some Space Wolves Grey to add some contrast without it getting away from the albino scheme.
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
