It's been quite some time since I've dreadged up this thread, but since this is for the dreadnought, I figured what the heck!
I've never been fond of the TLAC arm from forgeworld and having some extra IG autocannons laying around I decided to make my own. Unfortunately, the ammo drum on the bottom got slightly off true when I was gluing it and I wasn't able to pop it off. The other bits that might seem off are caused by the perspective distortion on the shoulder as it angles back. They are actually true.
I'm also about half way through painting up some epic marine bikes... and by some I mean 10 stands of three bikes and three attack bikes. I'm hoping for the end of the week with them and I'll post an update when they are done.
