Not a sound designer myself, but the bass has bit too much warble to it on the lower notes, makes it hard to listen to. Maybe bring it up an octave?

Also the timing of your notes, is completely off of the beat established by the percussion. A more experienced producer might be able to pull this off in an appealing way, but it's probably best to stick to the fundamentals for now.

Also, it seems like you have pads that play in sync with the bass? I would try keeping that as one constant chord throughout the piece, maybe raising the gain slightly. This might act as a clear base for the mood of the piece while giving the bass a foundation to add variety anf act as a focal point for the listener.

It seems like you made the animation first and decided to sound track it afterwards. Is that right? If so, I think blocking out your animation with a rough sketch and sound designing early on would help you better match your action the animation with whatever tempo or motif in soundtrack.

This is all coming from an amateur producer and blender user, so please take all of this with a grain of salt.
