Looking very good Charles, but I agree with Wojtek - it looks like two tones plus a light tone on the floats, with the light tone on the airframe looking quite light. But, it looks like the pics were done in bright sunlight, so that could be affecting things.
BTW, there was a reason for the British 'wavy' camouflage and the German 'angular' or 'splinter' camouflage. It was due to the territory being flown over the most - Britain, particularly the south, is mainly irregular field patterns, none of which are the same size or shape (dates back to the partioning of fields and the planting of hedgerows, in the 1700s), whereas in France, northern Europe and particularly Germany, the landscape was/is more 'angular', with regular shapes and sizes to agricultural land.
