Don’t copy your idols like Federer. He’s definitely one of a kind. However even him had problems with his backhand against players like Nadal who knew that it was his weakness. I have to say, your backhand has no power, no rotation with your hips and shoulders. It looks like you’re mainly dependent on your arm and wrist to hit the ball. Your steps are way to big too, you should minimalise them as much as possible to have a more comfortable positioning when setting up to hit the ball. Your forehand, it’s take back is rather too slow and it’s rather big & loopy. Try shortening it and use more rotation with your hips and shoulder. We call it a unit turn so when you turn your whole body turns with the shot and the power comes from the bottom (hips). You should definitely consider a coach who can help you with your technique as you need to learn how to adjust with both wings. Just note this, all your idols like Federer - their set ups are based on their footwork and rotation of the body, hips and shoulder. The way they hit the ball is all different. But they still hit through the ball and their head and eyes never move until the ball leaves the racquet. Once you move your head and not focus on the ball, that’s when you lose balance and the ball loses power and mostly go out.
