losing weight as a 15 year old

ive been overweight for a long time, at least 3 years now and ive been trying to lose weight by being in a calorie deficit and working out every day, sometimes twice a day, usually I use a treadmill or elliptical.

people recently have told me i look like ive lost weight, which is very encouraging for me but im not where I wanna be yet, is there any way I can speed up the process or lose face fat?
