So like virtually everyone else I've been working on Nurgle.
First up was a couple of trees, yeah I'll need a bunch more, but it was a starter for 10 to get me going, I don't want to overbuy on them.
Following on from that I started with adding Rotigus to my existing Nurgle stuff. This model is a joy to paint. You can do it with a basecoate & wash and it will look pretty decent, you can then spend as much time as you want pushing the shadows & highlights further and get all the cool effects you want, picking out details and basically doing fun stuff with the model.
