Nah man honestly you have it good. You get to use basically anything you think sounds cool to you since there's no voiceover or vlog like situation.
I can definitely recommend good places to get royalty free or creative commons music though:
- Incompetech
- Freesound
- Bensound
- FreePD
- CCMixter
- PacDV
- PublicDomain4u
- Not to mention YouTube's own creator music library.
And the music you used sounds good. Anything along those lines works
