I would say just play that same pattern with a metronome (or even better, use a metronome over the video you posted so you can see where you speed up and then slow down ....we al do it, this is not a criticism just a suggestion to improve). Other than that (and that you were mostly improvising), I would try to come up with a part that could be used in a song context, it doesn't have to be fast or super slow, but it has to be usable.
The reason I suggested he plays the same thing he played vs playing along to a song (my favorite thing to do) was because when you play along you have the original drummer as your guide, which makes it really hard to mess up timing. On the other hand when you play a drumless track, you are the timing (unless you are using a metronome). Playing his own composition (the noodling) will reveal how much or how little deviation from the proper timing he has.drum teacher/band director of 30+ years here:
you have pretty good sense of time, and your technique does not look too bad; the pattern itself is sort of "noodly", meaning that it sort of doesn't have direction, but it is not bad.
What styles do you like to listen to/ want to play? You have the ability to take on quite a few, it just needs direction. Like @GetAgrippa mentioned, maybe post an example of you playing along to a song, or an example of what you like
definitely a good start though!!!
If simple is NOT your thing... I challenge you to this:I would also suggest playing along with a drum-less music track, and do something simpler. You're very busy on that video sample. Not that it was bad, but keep in mind that as a drummer, you need to play very simple time when the music dictates it. Give us something with a "Money Beat," which is eighth note time on the hats, 1 & 3 on the kick, and 2 & 4 on the snare, and then put in some appropriate fills.
Also, I noticed that your bass drum is stuffed with something I couldn't identify. We've largely gone past the days of stuffing drums with lots of laundry. There are pre-muffled heads available that remove the need to fill your bass drum with who-knows-what. There's also old school felt strips, a time-tested way to cut down on ring, but they are still a viable choice. Gibralter sells them and they're inexpensive.
If money is tight for you and pricey pre-muffled heads are not an option, a medium size foam pillow that sits neatly at the bottom of the BD shell can be purchased from Walmart for a few bucks. Maybe your family even has an old couch pillow you could use. Good luck.
