A Battle standard bearer of the chaos god Slaanesh. He (yes, he) was formerly a imperial soldier, but has since become a herald of the Empire’s greatest foe, the forces of Chaos. His appearance has been twisted by the gifts of his new patron.

The upper body is that of a classic mounted daemonette, the lower is from a “Battle for Macragge” Genestealer. A sword and leg armour from the Empire Soldier frame have been added.

I failed to get a good shot of the banner itself, which is why it was omitted.
