Is this downtempo? I'm not sure I'd necessarily agree with that tag but it doesn't detract from the piece itself so it doesn't really affect my score.
I like the different sections of the piece, and that they maintain distinct motifs' without being incoherent. I do wish you had changed up the string melodies a bit, taking advantage of the beautiful sounds you can get from slow high strings as well as the slow low ones. However, that being said, the run you did make is very nice and catchy.
I'm not sure whether the kick is a bit too "hardstyle", maybe it could have been differently EQ'd to blend a bit better into the mix. Indeed, in the kick sections, the mix does become too bass heavy, and probably requires a different set of levels on the instruments than in the orchestral section. Only a subtle difference is required, but it will help your melodies sound less drowned out. You could considering a more subtle sidechaining with the kick to help it blend a bit more.
Overall, nice piece, could have used a bit more work though in regards to development and mixing.
