Good evening. I'm sorry, but the best I can do is what is sometimes called a 's*** sandwich', so... Well done on the video front; it's not easy to get all the elements synced up, with multiple views. Good work , there. What's 'less good'..? The mix. I listened through monitors, then with my headset, and had to compare to the original (I don't know the band or the track...), and your mix doesn't fare too well in comparison. There's a wall of low-end mush clouding it all, taking all the 'snap' out of the drums and solo spots (I couldn't distinguish cymbal hits at all...). It's been multi-tracked, and the result is far too dense, with complete loss of detail. A great pity, as the playing is very good (to judge from the video shots, not from the sonic result...). The ultra-low tuning is not doing you any favours, without some delicate filtering and EQ to be able to 'place' everything in its sonic space. The energy is there, the vocals that do come across are convincing; you can all play, no question, so 'Well done' on choosing and realising such a song. Take the stem tracks back for a re-mix, breath some clarity into it all, thin out the mush and retrieve the 'snap', I'd say.
