ho-ly... scheisse... i bloody love this one, the fading city in the bg, and the mech so close up, all the little details on the mech look amazing too!, and the mountain!, oh the mountain >w< amazing job! how long did this take you?
It's not uncommon for non-Blooded Warriors to use alternate configurations or custom configurations. The whole idea behind the omnimech and its podspace technology was that the load out could be changed on the fly to fit the mech to the situation, not force the situation on the mech.
Non standard load outs are common among Blood Named warriors. Phelan Kell/Ward would be an example of this when he was given a new Wolfhound re-built with Clan tech after he had gained the Ward Blood Name.
