Walker is a versatile forward with a well-rounded skill set. She is a legitimate knockdown shooter from the arc, stretching the floor as a reliable spot-up threat, while also protecting the rim and running the floor in transition for easy buckets. She rebounds effectively on both ends, shows advanced footwork for a forward working in the paint, and blocks shots well thanks to sound positioning and timing on her jump.

Walker projects as a 3-and-D wing at the next level, with good shooting mechanics, a quick release, and a preference for the corner 3. She has good size and athleticism, stays active on the boards, and likes to push the ball and run the break to get rewarded in transition. Defensively, her big wingspan and lateral quickness let her stay in front of drivers to the basket.
