It's definitely not bad in terms of SFX. It's just a matter of some music playing at the same time and the volume between different things. All the audio itself sounded great! It can get a bit complex to not have things overlap and sound weird but keeping things organised really helps with that, I think. I use Yoolean sound meter to check the volumes on everything because you can become deaf to volume differences if you're doing audio for hours at a time.
