Superb painting and scene setting Jan! As I already had the pleasure to see your work up close a few times I'm sure these are no exception. Clever use of the Marder too. I always thought it had a somewhat futuristic vibe to it.
Also very fine painting on those adventurers. Just a cause of bad luck running against Jans ruffians.
The work on the skin is very smooth and the white armour looks ace. I would have gone for a somewhat more neutral (grey for example) background though as the white is a tad too harsh in my opinion. Just my two cents though.
