For me though, I'm going to slowly work on an IG army as its what I used to play at Epic Scale. Not got much yet, and no plans to rush into it, got too much other stuff first. My old minis have provided a penal legion squad, psyker battle squad, and a couple of 'counts as' special characters. Then I've got a couple of sentinels, the vendetta, and about 20 guardsmen. Just enough for a legal force, although a pretty small and unbalanced one. For the guardsmen I've been experimenting more with washes. I remember liking the old GW washes, but not the range of colors. Then I discovered Payne's Gray. It's a blue gray that is perfect for shadows. So flat coat the guardsmen, bit of dry brush, and drown them in Payne's Gray wash. Put a unit out on the table and they look really good.
