I've finished off the six static platforms and built the three track units. I have held off from completing the multiple launchers for now.
I am really pleased with the way this Kickstarter has turned out:
1. Great value for my money.
2. No flaws or miscasts.
3. Minimal flash on the models.
4. On time.
To give you an idea of scale, here's the cannon platform with a GW Master of Ordnance and one of Curious Constructs' gunners.
