These guys are the last of a huge commission I've been doing for the past year or so. They are painted up a little better than tabletop so they can be used as a squad or broken up and used as Sergeant figures in other squads.
This biggest thing I did with these guys was clean up my brush work and then blend their shoulderpads. It's a small thing, but it helps make them stand out from the other guys who just have line highlighted shoulderpads. That and they have bone colored helemts which really pop against the black and purple armour.
You'll have to forgive all the white specs on his shoulderpad. I hadn't noticed them there until it was too late and the squad was already packed up for mailing. It's just the fine dust from cleaning other models nearby and it's not really part of the model.
In the end, purple is such a cool color for armour. You don't see it that often and it looks so sharp on the table.
As a side note, this is the squad that I tried painting the base first and I liked that I didn't have to worry about drybrushing the highlights on the base with a completed model in the way.
In this case it's for a Hawk Lord marine, but the purple is the same and I've included some weathering tips in there as well.
You can look though the rest of the project here.
