Santa Cruz Garter - Sex please!

[Coolsox]

Hi everyone, I recently purchased an unrelated pair of santa Cruz Garters (Thamnophis atratus ssp atratus)
The seller has contacted me to advise that he may have mixed the sexes up, and wanted to be certain that we both had a male and female. Now I've looked through the sexing article on this forum and I am 99.9% certain I have a pair, but would like to hear other peoples opinions.

I managed to keep them still long enough to take a couple of quick pics!

Suspected female:
