You're facing fully away from the target before your X-step, that X-step with the right foot is similarly facing completely away from your apparent line (off the right corner off the box). So by far the biggest thing you should work on is your footwork and timing:

• Stay side-on in your walk up and into the X-step.
• You put your toe down in the X-step first, which is good, but this shouldn't be angled so extremely away from the target. I'd recommend trying to plant it 90 degrees (perpendicular) to your intended line at first to really try and keep facing sideways. As your form improves the X-step foot can actually be angled a bit away from the target and that's an area you will see a lot of variance in good form, but the main thing to focus on is not turning your entire body away from the target at this point, so aiming for 90 will help reinforce that.
• Try and stay on the toe of this foot throughout the X-step as well rather than relaxing back into the heel. Push with your X-step forwards into the plant step, rather than coming down vertically onto it, like you're trying to stop your forward momentum quickly.
• By far the biggest thing is going to be improving timing by not turning away from the target so early. Begin to rotate your shoulders and hips away from the target only after your X-step is down and your plant foot is making its way forward. You want to be at your maximum coil away from the target at the instant your plant foot is coming down, which is when you fire your hips and off-arm. Your shoulders lag behind this, accelerating into the hit point.
• Your throwing arm generally looks decent, though I'm not a fan of having the disc out in front as you start the runup myself, but plenty of people and pros do something similar, so if you're doing the rest right that's not necessarily super problematic. Power pocket looks solid and I like how your elbow stays up and out, not collapsing towards the body, and looks like good extension out away from the body at the hit point.
• The release is a little nose up, so try focusing a bit on really "pouring the coffee" or supinating a bit more. But it's important not to let that stiffen up your wrist so that it doesn't flick at the point of impact. It's not possible to tell what you're doing from the video, but it looks ok. So much speed and spin comes from having that wrist loose such that it coils coming out of the power pocket and snaps forward at the hit point as your arm hits full extension. So if your stiffen up that wrist while working on getting the nose down and the rest of it then it can very much be one step forwards, two steps back.

Overall I'd say you've got a solid foundation to work from though. Ultimately everything can be improved and that can be disheartening and it's tough to know what to focus on as a priority, but those would be my recommendations that should start to see the biggest improvements.
