Great recording
Much better than your past recording of the song. The vocals are a lot better in tune with the song.
1. Don't sing too loud in some parts, blues is a mellow feel feel, and you usually need to change the volume in studio on the computer when you do sing louder.
2. The blues fall isn't a change in tempo, so keep the tempo.
3. Try to keep guitar parts to short bursts not interrupting vocals.
