I like that now finished poster style painting. Excellent.
As to the one sold on e-Bay; I wonder whether the buyer's husband just might be a member of this forum?
Finally, that new half finished one with the wintery sky and grey sea - that is looking very promising and atmospheric. Funnily enough I did a painting myself in virtually identical light conditions, albeit not of QE2 but of a steam train; I sold it as a result of my recent exhibition but I still see it nearly every day because, believe it or not, all the staff at work liked it so much they clubbed together without my knowledge to buy it for the office!
Although somewhat off topic, I've attached an image of it here so we can compare our respective techniques for wintery light conditions - that much is certainly on topic...
