That looks like a lot of fun, great finish on the sub too, that's very lifelike, there's a very convincing sheen to the surface colour. Just need to dye the swimming pool the same colour as the Atlantic and you'll be in business.
Incidentally, both times I've tried to register at Subpirates forums, it says I should get an email confirming it's been enabled by the moderator, but that never happened on the two occasions I tried to register, so if anyone who actually can post on that site reads this, do you know why that might be so?
