Is this any good for losing weight?

I'm very embarrassed about the picture of me, I could literally cry so please be nice to me. I'm trying really hard to lose weight. But I'm 240, 5'2". I do this routine with about 30 minutes of cardio on the treadmill after (I use an app that tells me to walk and then brisk walk for x period of time)..is this any good to loose weight? I've been watching my calories and stuff too and eating a lot better. But yea, what can I do to improve this routine so I can improve my body.
