This is an excellent ship set, Atrocities.
The carriers are excellent as they are, but I thought of a couple of things for detail (please take these suggestions with a grain of salt). Is is possible to add text to the textures in Doga? If so, you could place a large numeral at the end of the flight deck (or on the hull for the battleships, etc.). Also, when you get the fighters finished, you could shrink one down and make copies, and scatter them around the flight deck for effect.
Just a couple thoughts for your consideration...
