The Warp Storm

So I picked up the Killdakka box, and started slowly assembling it. Got the jet finished, but unsure what to add to it to make it a fully fleshed out army. What do yall suggest?

I wouldn't worry too much about adding to it just yet, personally. The Killdakka box is a pretty good starting point for an army, and once you've got it built up and painted you'll already have a solid little army
Are you planning on a single Clan, or multiple throughout the army?
