That's an awesome Battle Wagon! Not only does it look orky (and totally consistent with the
GW ork look), it has almost exactly the same profile as the official model!
So many times a model looks totally sweet, but it's way bigger or smaller than the
GW model. I don't have a problem with that, but I know that it can really cause arguments with some tables.
Other times, the model looks fantastic, but it doesn't look like it belongs in
40K. It might be really cool, but it has a different esthetic.
You managed to avoid both of those. That thing looks like an alternate sculpt that didn't get produced!
