I really like this! The drums are nice and fast, and that guitar riff is just intense! It could be mixed a little quieter. Not that loud is an issue, but it is when it's this loud. Also one thing to point out, for a loop, this isn't quite seamless. There's silent audio at the end for a second, and the beginning of it is slient for a fraction of a second. If someone wanted to use this, they'd have to edit it themselves to make it more seamless. Remember, for a loop to sound right, it's gotta be seamless, when there's bits of silence or clicks and pops at the start or end it doesn't loop perfectly. Overall this is a great idea, and my only advice is: Mix it just a LITTLE bit quieter, and make sure there's no silence at the start or end next time so it loops perfectly. Mine loop perfectly, of course you can't tell by listening on NG because NG doesn't play it seamlessly but download any loop of mine and you'll be able to tell. Plus, looking at the waveform alone sort of tells you where it's silent and how seamless the loop really is.
