They look very WWII French for some reason? Colour scheme I reckon. It may be the camera washing out the shade, but have you thought about washing the leather parts with Badab Black/Nuln Oil? It does the leather look sweetly, and quickly. Good start. Like the Commander paint job, set apart from the rest, more bling-ed and his pose helps i guess.
Just a suggestion, but not a critisism although it sounds like one, sry. The bases are not 'muddy' enough prehaps for a siege trench warfare army? Just my taste, they are fine as they are but - Krieg=Mud.

Maybe ease off on the static grass and incorporate some wooden plank 'duck boards' or something similar?
I had a Krieg army all unbuilt and finally gave up (i'm a Power Armour junkie with not enough time anyway) and sold it all. Good to see some Krieg being painted! Well done Sir.
