Iron Warriors test paintjob, went with a muddy trench base. Looks pretty gritty but it might be too dark overall, debating on shifting to a lighter tan wasteland or red mars basing style.
I might do test models for other legions too, and whichever end result I like the most might end up being the army I pick. Or maybe i'll just forget about it and do historical WW2 stuff and save some money.
