Si: I have to say that class of ship certainly has a beautiful shape. I think I'm really starting to like the early steel ships.
Guido: You can't go wrong as far as subject matter goes, that's part of the idea behind this campaign. I know you enjoy building ships, and you are certainly well skilled in building aircraft, so you may want to choose a gun or tank. The Emhar and Tauro kits need quite a bit of work and would present a nice challenge if you're up for it

Alan: Me too, the more the merrier

Robby: Automotive brake fluid has been used by many to clean botched paint jobs off of model kits, it will warp the plastic if left in too long though. Some people use an oven cleaner product as well, but it is very caustic and smells pretty bad. They both do the job nicely.
It looks like you hand brushed the preshading on the wings? IIf so, you may want to consider airbrushing during this step after you remove the old paint. It will eliminate the raised texture.
Regarding the rest of the painting, what brands of paints are you using? And I am guessing you are applying the paint directly to the bare plastic?
