City, who came second in the curtailed 2019-20 Women's Super League season, are sixth in the table after two games and have scored just two goals. In contrast, league leaders Arsenal have scored 15 goals in their opening two games.
"It's both exciting and challenging because we had so many chance in both games that we've played thus far," Beckie told ESPN.
"We got out of the Villa result with two goals from good defensive pressure but I think we have had to re-evaluate our ability to score goals. We're creating opportunities which is obviously fantastic but we need to flip the switch on finishing teams early."
"Credit to Brighton, they gave us a tough game and we were obviously able to steal a point from us," Beckie added.
"After the international break, a lot of the girls went away to be with England -- there were some of us who stayed -- so we just got back together as a team earlier this week and definitely looking super positive going into the weekend and into a really really busy spell of games."
This season marks the first in charge for City manager Gareth Taylor who previously worked with the club's academy. The former Wales international spent his first few months in charge communicating with his squad online as the coronavirus pandemic forced the team to halt training and games.
"Obviously he took over the team in a really difficult place because there were a few of us that new him from being around the academy the last few years but we've also brought in a lot of new players that he will not have physically met until they're here ready to play," Beckie said.
"I think he has done brilliantly so far communicating what he wants out of us. He's very clear about what he wants and I think as a player that's good because there's no blurred lines. It's quite black and white.
"The way he wants us to play is definitely a style of really beautiful football that we're definitely capable of playing and I think fans will have seen us create so many chances through this new playing style and now it's just about that final piece."
If City beat Championship side Leicester on Sunday they will face either Arsenal or Tottenham in the semifinal with the final to be held on Nov. 1 in Wembley.
