Here are some pics of the 'entire' Death Rider squadron, well, at least the painted part. I made these pictures quickly after a rough and tough battle against orks, they quality is quite bad but they give an overview of a 22 men squadron on the table.
During the game the platoon commander and his squad thunder past to get into position for a charge of a unit of 20 boyz. Together with a second squad of 6 riders they were able to wipe them out (before being crushed by Meganobz themselves).
"After battle shots" of the entire squad (minus the commander and vox-caster which I missed as they were scoring some points on the far end of the table poking at some buggies). You can see the charging and prancing horse in the center, as well as the flag and the rider standing next to his horse.
A bad pic of the commander and his converted command squad: Vox-caster, Regimental banner, dismounted rider and rider with a pistol.
