I totally agree with that1guy, but this isn't a bad effort. I've seen some seriously terrible conversions using just some simple bits.
My biggest pet peeve for my own stuff is using say, chaos spikes for an ork vehicle. Even if it suits it fine, it will drive me nuts eventually.

The thing that sticks out to me is that the banner shouldn't be angled like that since it's standing still on an incline. Really like the grating on the front though.
This looks like an ork looted dread. Why do CSM players always go for cheep/overpowered conversions? What I wouldn't give to see a small unit of nurgle marines leading an massive army of zombies into the meat grinder.
