Saw these on FB and I have to say first off, I am not entirely unhappy with the direction Warcradle are heading.
The French ship is rather nice, although the bridge change to a Montmatre-style rather than the flying bridge is a bit jarring, overall it's a decent style and does fit in with the originals. All that "gingerbread" on the hulls seems to be a follow on to the Magnate and other later Spartan designs, and to me, it's somewhat unnecessary on most factions ( The League Of Crimson have a
great reason or two for such frippery, but leave that aside ).
I have to disagree with RuleBritannia in the main on the British flier here; The lower wing modded to include undercarriage and the bulk of weapons is rather clever, and the other visual nods are not badly done. That turret, though . . . Mind you, not shared here is the Prussian Fighter which is basically the same as it's tiny flier counterpart in DW but with the fuselage of an FW-190 and steampunk details, it really does work.
The Russian flier looks like a Mig15/Me-262 hybrid with no air intakes, and frankly strikes me as looking unfinished - and as Stuart kinda indicated these were just early sketches, I'm confident sanity will come through.
However, as I said at the beginning, there is clearly some attempt to maintain the style from the originals, and its looking pretty good.
