Vocals
I'm really not feeling the vocals, I recommend to either practice a bit more on them or find another singer. If you really do like singing and really want to be the leadvocalist of the band, I recommend you just take your guitar, play any note and hum together with it. Also, the falsetto is off, a lot. You can improve that by learning how to sing from the diaphragm. An exercise I used was just to lay down on my bed, and carefully breathing from the stomach.
The instrumentals were good, but if you would turn down the chorus on the guitar, it would sound a lot better.
Other than that, good job, mate.
