My favourite artist...
Vadim Voitekhovitch has a moody and atmospheric style that I like to use to illustrate the Steampunk worlds I build in my head.
I have used his images to illustrate my Airship Design posts, mainly because his airships are both whimsical and apparently practical. The scenes are serene but complex. The environments are rich and detailed without being chaotic.
You can see them in detail here at the Steampunk Art of *Voitv
This is a world I could quite happily inhabit!
Keep your sightglass full, your firebox trimmed and your water iced.
