The 31-year-old replaced Hope Powell in December and will lead them into this week's Cyprus Cup.
"There's been a boost in the players' mentality," the 22-year-old told BBC Sport.
"Mark has brought in a lot of new faces and that brings better competition for places and brings us on as players."
Defending champions England's first match of the tournament is against Italy on Wednesday.
