Any tips regarding workout?

This pictures are 2 weeks apart. I tried Chloe's ab workout to loose fat and gain more definition.
Currently I'm thinking of following this workout plan: (45 min each day)
Day 1: Leg workout mainly and a little ab workout
Day 2 : Ab workout
Day 3 : Full body HIIT
DAY 4 REST
DAY 5 - Upper body
Day 6 Ab workout
Day 7 - same as Day 1
Day 8 rest

Will this be all right? any tips?
