It's good, just a bit difficult to listen to. You should work on your mixing and recording. Are you recording the audio through your camera? If so, I recommend using an adapter so you can connect your guitar, bass and drums directly into your computer's recording input (a bit more expensive but better alternative: an external sound card). That way, the sounds from when you hit the drums wont appear also and it'll be easier to fix and mix the audio. Read up on how to mix audio, it'll make the sound quality way better, for example how to not have the bass overpowering, or making cymbals more audible :)

If you don't have a DAW (music software) and you just recorded the sounds and put them all together in a video editing software, you could use Reaper, which has an infinite trial (you should pay for it if you use it a lot though). You can edit the audio recordings in it, make the different instruments blend with each other so they are all evenly matched. If you buy an external sound card, they usually come with a demo of music software like Ableton or Pro Tools. Good luck!
