Its probably just the picture making their bases look bigger, they are definitely on 40mm ones. Probably because I haven't green-edged them yet like the Herald and Fiends and they blendinto the black movement tray a bit (in fact, a large part of the army was painted in the 3 days before the event, which is why I didn't take any close-ups of my models!).
The special missions I liked, but I would have preferred something a little bit simpler just to make picking the missions quicker and easier. Having a special terrain piece was quite nice (ours definitely helped in a few games) but led to some cheesy combos as you saw. From what I could tell Wyrding Wells, Wizards Towers and Anvil's of Vaul were all pretty popular. Without them though, all the terrain would have been basic apart from the mysterious forests, and I rather like the terrain rules (mainly because hardcore competitive players
don't 
). According to the rulespack for next year both the special missions and themed terrain aren't in it anymore. I can take or leave the terrain but I'll miss the missions as I think they add an extra dimension to the game.
Anyway, thanks for your comments and glad you enjoyed it.

It was pretty packed, but it was only really a problem in games 2 and 3 where our table was at the end of the row up against the 'castle' wall (as you should be able to see in the photos). The tables were set up in rows of 3 so it was a lot easier to get around than it has been in the past when they were set up in much longer rows. Also you end up a bit dehydrated if you aren't careful as with 4 people involved in every game you end up talking near-constantly. To make up for that, Bugman's adjoins the gaming hall and one of the staff comes round to take drink orders from you mid-game so you don't have to stop gaming, which is nice. By the end of the weekend you do end up pretty exhausted but I'd still recommend it to anyone who likes some friendly competition against new opponents.
