Tyranids are a "recent" development in 40k, so Papa Smurf wouldn't have encountered them, so him standing next to a titan with nids painted all over it'd shoulder is weird. Not a huge concern, and I'm sure most people wouldn't care, but I find it distracting.
The stasis field is down, the Primarch returned, the Imperium again crusades and the starchild somewhere reborn! All hail Warhammer 41K, where in the further far future there is only noble brightness!Is that mK7 armour next to a living Primarch on the base? That looks weird.
