Juless UI/UX Designer

This is a part of selling screens and screens for App Store for a Fitness app. The target audience are american women 20-40 years old. So the color palette was chosen to fit this audience. The idea was to keep attention of users in Appstore by emotions how women will look like after using this app - slim, sporty and active. Energetically photos are too sporty and positive and should stand out of other screens from App Store. What do you think?

New inspiration for you guys. What do you think if look like this?
