While the Ulysses and Ursa obviously still need a lot of work, the Ares texture definately is a *very* good start on improvement.
What's making it look a bit 'unfinished' is that it is too 'perfect' for the model. You'll need to edit in little damaged parts, certain specks and/or bumps. Also, I suggest lowering the contrast a bit, as it looks too sharp in some parts.
The best image to show it is here:
see the lines between the metal plates, theres a visible "line inside the line", or the plates on top of the wing, they're weak and line up in the original, whereas the contrast in your image makes them seem to 'disappear' to an empty hull (looking cut-off) - if you'd additionally try to smoothe the pixelated shading that still looks through from the original maps they would be perfect.
Else than that, the Ares is really pretty.
