Hey Diego!
Nice tune! I like how the mix starts, but later on it feels like it's either clipping or overcompressed. I would also really mind hihat and percussion levels, a lot of them might sound better if they are quieter, so that the beat feels more together. As a rule, I make hihats really-really quiet, this is one of the major tips of writing techno. Usually you reduce the loudness of the hiahat to 0 and then increase its loudness until you can make it out, but not louder than that.
I would also reduce the lows on most of the elements, by about 1.38 when the claps starts it becomes really crowded. I like the string at 6.20, very clean, but the mix itself is not breathing at this point and feels a bit flat, whereas I want to feel the dynamics and the groove. And what's interesting, the mix itself sound relatively clean, so a bit more dynamics could really make it awesome.
Cheers!
