First Mix, Need Help

Not bad, but like you said in the song, the guitar playing definitely needs to be tighter.
It might just be me, but it sounds like the guitars definitely have some unwanted low buildup. Could be the sound you're going for though.
The snare I really think should change.... sounds way too much like a clap and not a snare. This could help the guitars glue with the drums better (along with tighter playing)
 
Thanks for your comment !
I try to have a good guitar sound, but no way, it's impossible, i record my sound with the SM57, an my dual rectifier head and his oversized cab ! And after many hours of tweaking, the sound is too numeric for guitar i don't understand ...

But i will work harder !
