Seems like I've been on a Nurgle run lately, having fun with all of the different looks. Its quickly becoming my second favorite thingto do with chaos space marines, behind the Wordbearers.
The Nurgle Ogryn conversions I did a while back really opened my eyes to using a few more techniques in creating them. The detail of the Forge World nurgle stuff is simply awesome.
Since doing a bunch of conversions up, using the plastic ork nobs, I have a bunch of these magazines left over, so I thought a drum mag would look on the bolter.
Next up, probably more chaos, but I also have a Batman Space Marine that I'm working on. The Predator will also be coming soon.
