I picked up Operation: Icestorm a few days ago, and also one of the new Combined Army starters (which is amazing). The new Infinity models are so cool I had to pick some up. Light-years ahead of the older sculpts.
So far I’ve painted 4 nomads, and I’m about half way through the Maakrep sniper. I decided to really take my time on the Combined Army models, and do fast paint-jobs for the Operation: Icestorm minis. These figures are 2 hours of painting each, including basing but not counting prep time. I think that’s about my sweet spot for figures I can be proud to put on a table without taking a ton of time for each model. Two-brush blending for the win!
