Its possible that Luna and Cele used to partake in “friendly” bouts during their early lives. Times has moved on and things have changed. The art of fencing becoming a victim to the sands of time, but still available in the form of a niche sport; however, some habits die hard. And these two sisters always did like the more physical version of chess anyways…
 

 
For those curious, the swords have rubber tips at the end to prevent you from impaling the other person while practicing. While this could be Épée, I think it would make more sense to practice foil since the “target area” is only the torso, allows for a good pacing of the bout, and more “fluid” exchange of attacks and ripostes.
 
 
Scene is bland, but I focused more on clothing and pose. Lighting was a bit tricky, but the main subjects should be illuminated well. It was difficult to get the pose to maintain a relaxed posture while having good fencing form, with perhaps the most difficulty being the off hand. Unfortunately, the weapon hands were extremely difficult to form. Other than that, poster turned out all right.
