Vocals are not very good, you lack consistency and proper enunciation. Can't get away with that when covering Mikael's vocals. I'm not saying stop trying, just saying you need some more work, maybe pick an easier or slower song/vocalist. The slower part towards to end end where you were not trying to keep up to the pace was better.
Thanks for pointing about the title, don't know how I didn't noticed it earlier)
And thanks Belac for advice, will try more! Though maybe you could give some name of band where vocalist is slower? Thanks.
