Looks like a good masking job to me Rob! Wayne's right, the pattern is not quite right, but it might be a bit of a job to re-mask, it's up to you.
If you'd like the actual patterns for 'A Scheme' and 'B Scheme', I can post them. The difference was dependant on the serial number; odd numbers had one scheme, even numbers the other. This was a standard pattern on all day fighters throughout WW2, regardless of colours.
