Hey man, kudos for throwing your stuff out there. Metalcore is not exactly my cup of tea, but my singer and drummer like it, so I've listened to quite a bit of it in spite of protest
So you've asked for an opinion, and I'll give you my 0.02$
First track- band sounds tight, but your singer is out of sync- I just don't like throwing out lyrics without thinking about rhythm or the cadence of the song, which he does at the beginning of the song. Otherwise, pretty tight.
Second track- better. Your band is still tight, but the singer seems more musical and focused.
I think you guys have potential, just need to bring all parts in a little more.
