SOASE has some really good art guys, I wish they would be let off of their leashes more often!
Here's a link to a post by one of them when he was given a free hand to post some Entrenchment work.
EDIT: The post has seemingly been nerfed, but if you click the 'external link' button at the top of his post, it will take you to his gallery, and there is a selection for Sins of a Solar Empire there, in addition to a lot of his other stuff.
