I need weight advice!

Hi everyone, I was going to post in a weight loss group, but it doesn’t seem very active so I decided to post here in hopes to get a lot of replies. These photos were taken tonight :

Here is me a couple years ago, I was probably around 230-234

I am 5 foot 7, I used to weight 234lbs but I’m down 20 lbs to 214lbs. I have big boobs as you can see, I’m wearing a sports bra which kind of flattens them out a bit, but I’m a J cup and they probably weight about 10-20lbs. So I’m at 214 lbs and im telling myself I need to lose about 60-70lbs more to be healthy ( 144-154 range) but I’m thinking that won’t be right , my mom when she was younger was 125 lbs with DD breasts, when I was around 175 lbs I was wearing somewhere between a DDD and G so I’m thinking my boobs aren’t going to shrink down past DD. All that aside, I don’t have very big arms or legs, I carry most of my weight on my stomach, chest and I have back fat. So what I would like to ask is how much weight it looks like I need to lose off my stomach ( I’m looking to get to a flat stomach and then work on toning my abs, and whole body really) I’m also wondering if there is anyone who has a similar body to mine ( with big boobs and all) and how much weight they had to lose. Here is some more photos, do you see any change ?

Also here is a comparison from September 4th and 11th on my back, Just wondering if I’m losing any from my back

I’ve changed my whole way of eating and I’m adding exercising. I have a rotator cuff injury from a car accident so I’m slowly introducing work outs other than walking and just taking it easy as I don’t want to set my arm back. Sorry for the long post and Thank you so much for reading. I appreciate any input I get☺️ I hope everyone has an awesome day!
