Shayna wishes she was like this when she still did MMA. I haven't seen any of her Shimmer stuff, but I have seen her Stardom stuff and she seemed perfectly fine in longer more competitive stuff for the most part.
Io tried to make her stuff look deadly.
As for what she could work on:
-Her punches and kicks need more sauce on them.
-She slaps her thigh for strikes too early sometimes.
-She moves like she's wearing really heavy boots and comes off unnaturally slow and stilted at times.
Very curious as to what happens with Sonya Deville going forward. Shayna has size, cred and association going for her. Plus she was booked better in this tournament than Sonya has been during her entire NXT run. From August of 2016 until May of this year when they changed her name, she was presented as this badass MMA chick yet lost every match she had. Sonya has a solid look, moves better and has the LGBT thing going for her, but she only appears sporadically and still hasn't really clicked with the audience.
