Rhythm's better, especially during the first minute. After that the left bass is leading the beat a lot but I like its tone - kind of bright and growly. The two basses are getting good tones for separation of the parts and musical interest. Mucially, the listener's gotta be watching for small details in this.... more of an eastern approach to repetition with subtle variations.
Can be tough to track along with a sparse rhythm track like this. If you’re not doing it already, you might try using a busier sampled drum part in the bassist’s headphones for monitoring while tracking, but leave just the sparse drum track in the final mix if you prefer.
