really nice man!
yeah, i heard the clipping a bit when the cymbals were on in the start, and aswell when the doublepedaling started. Especially at 1:46... but fuck, you really should redo the mixing cause this shit is gold!
If you want it fixed, just lower the output volume of your master in whatever DAW you use, then take the mixdown, normalize it, use a multiband compressor and give it a few tweaks, normalize again, add some mastering EQs, whatever, then give it maybe a 25-30% loudness boost. Do a final normalization to get it up to 0 dB and it should be fixed.
Love the riffing!
