Thank you, guys!
But I have to stress that the paint kit provided for this aeroplane made things very easy (except those tapering lines...).
The only things I had to add basically were the black deicer area on the upper part of the fin and the larger black mask around the front windows. Some decent exhaust stains on the horizontal stabilizer of course had to be added too (can't live without it...), although I'm not quite sure whether the Garretts are as smoky as the Twin Otter's P&W PT6 turbines...
Nice shot over Tauranga, Charl!
@ Sean:
Thanks for your suggestions!
But I think I'll stick to NZAM's ZK-CDK:
Besides its current "sale" livery, the older, red striped version, shown here

Cheers,
