I just finished new converted Tyrant for my Gutbusters - some day I want to try out running two tyrant list. But mostly I just wanted to paint the Blood Bowl Ogre and kitbash some weapons to him. I really like the dynamic pose of the model. It's very good alternative to any Gutbuster hero model. Or it can well be made into Maneaters. My next idea is to convert an additional Butcher from the same Blood Bowl model, but this requires a bit more than just kitbashing.
I added some pictures for comparison as well - Blood Bowl Ogre compared to normal ogor and my firts converted Tyrant. I was a bit worried that Blood Bowl ogor is too small and don't match, but you can hardly say that. He might be a little bit smaller, but that can easily changed with higher base and big weapon.
