I find most of his images fascinating because he creates an almost-believable world of circa-1900 European cities and towns where airships and other never-quite-happened contraptions abound. Besides his attention to detail, Voitekhovitch gives his scenes believable atmospherics. Northern Europe is gloomy a good part of the year, after all.
The coal-fired warships are similar to 1890s French cuirassés designs such as the Masséna, featuring extreme tumble-home sides and ram bows. The airships also seem to have coal-fired steam engines: note the dark smoke from their stacks.
Harbor scene. I like the rust on the battleship -- it makes the scene more believable.
Setting off to war, though the people seem indifferent aside from the woman near the cannon and another with her young son near the stairway.
Details include what might be a steam-powered omnibus and an airship "carrier."
Loading mail aboard from the rickety tower.
Two scenes with airships, while the rest of the technology is pre-automobile.
The nearest airship is attached to a loading platform.
Again, no cars.
