Self Portrait - New Strobe Test

I just bought a used Sigma EF-500 flash and wanted to put it to the test.

Here's the rundown on how I lit it—

I used the new flash as the main light, diffused through a white umbrella. The rim lights are created by snooted Vivitar 285HVs behind the subject (me!) at 45º angles.

The Vivitar strobes were triggered by Cactus V2s and the new strobe was triggered via its built in slave (it fires when its sensor sees another flash pop).
