Sexing Asian Forest Scorpion Help?

[MES]

Hi everyone!
I'm working on a breeding project, and I bought this suspected male/female pair. Based on these pictures, can you tell me which you think is the male and which you think is the female? I suspect the first image is the male, and the second the female. Thanks!
PS - don't mind my protected hands, I'm kind of a wimp and didn't feel like getting stung or pinched haha

 

[The Mantis Menagerie]

I think the first one is a female, and the second one is a male.

 

[Dry Desert]

I think the first one is a female, and the second one is a male.

Pictures not overly clear, if you could place scorpions in clean cricket tub or similar and photo from below would probably show more detail.
As it is the first one looks to be female, the second male - not 100% due to photos.

Thanks! I will try to get some better pictures!
