Paige VanZant's getting a peer review of her Power Slap debut ... with fellow competitor Sheena Bathory telling TMZ Sports it was overall a good performance -- but there's one thing in particular that caught her attention.
The former UFC fighter went up against Christine Wolmarans in Power Slap 8 last week ... the first-ever slap battle of her combat sports career.
VanZant knocked Wolmaran down twice in the four-round match and withstood her opponent's hard strikes .
