The dorsal appears to have dark color in it, but none of the shots show that area clear enough to be sure. Dark color in the dorsal is a female trait.
It would be best if you could get a shot with the dorsal extended, and with enough light on it to truly show and bring out the colors.
Not criticizing your photos, just saying what you need to show, if you want a good answer.
