It's alright
I like the pattern, but after the first five seconds I would have really liked to hear some variation, whether rhytmic, melodic or textural. And because I can hear the potential in this I'm going to criticize it to the best of my abilities.
In my opinion, the same accents over and over again get repetitive, so I would have tried doing something with the violin/viola that's at the top of the mix. There is so much that could be done to make it interesting, even in 35 seconds. Expected accents could be left out, or it could switch roles with the bass/cello on some notes. I would have expected more tension, leading to a more significant release.
However, I believe you wanted to add some melody instead at ~00:20, which would be fine, but why is it in the background? It is overwhelmed by what should be its accompaniment. In this situation I would have expected a change in dynamics to bring that melody to focus! One can barely hear it as it is now.
But let's move from the bad to the good. Out of the individual instruments, I'm amazed by the bass. Especially in the beginning, before ~20, it brings much needed variation to the rhythm and gives a feeling of movement.
In general, I think you have a very good foundation for an orchestral piece. And that is also why I cannot give it a 10/10. It is very good for a first try, I get the impression that you know your music theory. And I look forward to hearing your 2nd attempt!
