That's darned good, and pretty much rock-steady. The key is to go s-l-o-w-l-y, as you're doing; it's by far the fastest way forward. S-l-o-w is the new fast.
A word..? There are two schools of bass drum pedal: heel up and heel down. I see that you're 'heel up'; it might be worth doing exactly the same exercises 'heel down'; this brings into play different muscles and tendons, and is very useful for expression and finesse. As it is, you're 'burying' the beater into the skin; it's useful to have the beater strike, then come off the skin, without rebound, in the same way as your sticks don't stay down on the drum head. Discuss, maybe with your tutor..? A looser grip of the snare stick (a more supple wrist..?) would be something to think about, too, right from the start. Again, your tutor will have advice on these minor points. Good Stuff; here's my usual encouraging phrase...
'It's the first forty years that are the hardest, after which things, sometimes, tend to get slightly better'. You're doing well.
