It's a good attempt but I think there is a lot of room for improvement. As I Am is a song that I actually love to sing the same with These Walls. I'm hoping I can join in the idea of cover vocals. I would love to do Wither, but I have a LOT of trouble with that song. I either hit it or I'm off, way off.
Also don't try to sound like someone. your voice is your unique signature. Use that signature to its potential and create music from that. I sing DT every now and then but use my own voice which in many ways sounds a bit like Bellamy.
Also, Tick that's some good stuff.
