Thanks very much for all for the supportive comments.
Agree I needed to have an overall battlefield pic, and work on composition generally (too many references to stuff "out of shot").
Will get the earlier game up too (orks versus IG), though that will be missing the battlefield at a glance shot as well.
As for the HQ troops when playing second edition they were immune to morale checks, but i'm not sure about that now. We play they test as everything else does but if that's wrong please advise.
On Command units generally can people confirm that Gargants are not command units - i.e they must be given normal orders and not get auto first fire/charge. The requirement to have one as a leader for a 3 clan army confused the issue a little - though I think the fact that a Boss gargant isn;t a command unit in a gargant big mob helps point it in the right direction.
