England Women made it three wins from three with victory over Ireland at the weekend and now lead the Six Nations table.
The team face Wales next at the Twickenham Stoop and Hunter says her side will have to improve in two weeks time.
“It is now all about rest, recovery and analysis because, although we won against Ireland, it wasn’t perfect,” she said.
“We can always get better and better. We’ll go away, review the areas we need to work on, and we play Wales in a couple of weeks.”
