Inspiration behind gun shot

Due to lack of equipment we have struggled with the gun shot scene in which Nathan shoots Hao Zheng. Originally we wanted to just have a shot of Nathan shooting Howard with blood going everywhere in slow motion, with a juxtaposing song playing in the background. However we can't edit blood in because it will look cheap, and we can't use a blood substitute because we can't ruin the location. What we came up with was Nathan holding the gun, the screen going black and a gunshot being fired. The idea is inspired by the [spoiler] scene where Jesse shoots Gale in Breaking Bad. It is filmed from the point of view of Gale, looking at the gun being fired.
