Here are my acolyte Crusaders equipped as standard w Power Weapon and Storm Shield. I used the Cadian models as my other acolytes are such and it was better suited to my theme. Additional parts aside from Cadian bodies are modified Cadian backpacks, Empire shields, Grey Knight Falchions as PW's and guitar wire for power cables to 'amp' up the look of the shields.
Sorry for the quality of the photos, I was outside and it was overcast so the lighting was poor.
