You're quite the self-deprecating contestant, something I honestly wasn't expecting. It's more about the experience of participating to an event welcomes people from all over the world, listening to their music, hearing their feedback and their own voices. No one here is the best and my job as a judge is not even to put your track on a balance in an attempt to "measure" its value, because it's simply impossible.
Now, I think your track is well composed, it has a solid structure and you've managed to bring some degree of variety throughout these six minutes and counting of music. I would be stupid to not recognize some highlights from this effort, like the constant bass work which is pretty complex and interesting to hear, and all the build-ups and changes you've performed.
If anything, I would have loved to hear some more complex dynamics between the various melodies, possibly by adding background synths and ambiances, and sidechaining pads could have also helped the cause. The drums are not exactly immersive and I would have used some more intense samples, especially in the more downtempo parts. Try also to smooth transitions between the different sections with some riser sound effects, booms or even glitch effects that could help improving the flow of the track.
It's not what I consider a mediocre effort, and my rating shouldn't let you kick the bucket and seek something else to do. I encourage you to keep going down this road and try to give depth to simpler songs and patterns before moving onto something gargantuan like a 6-minute song. Also... djent? Pfft, got nothing on this. So far I haven't even seen any track can remotely be considered "metal", if that helps.
