Is 30kg lbs. a good weight loss goal?

So I really want to be thin and pretty I’m thinking that at least 30 kg is a good goal at least for now but I’m not sure and want other’s opinions.

So I 17f , am currently overweight at 105 lbs while I’m 5 foot tall.

Is this a good weight goal? Any advice? What do you think?

Thanks!
