Well, you need pics with the tail in order to sex them. That said, from what I can see, it looks like you got the genders right. I'm not the best pygmy sex-er though, so I would post better pics and wait for others to confirm it.
You can look at the dorsal crest too. The tails may actually vary in length a bit, which can sometimes make it difficult to sex them. Female brevicaudatus have a 'rounded' dorsal crest, males have a more serrated crest.
