the reverb is a little loud for my taste, also the vocals could be more in tune in parts, especially at 2:34 onwards in the middle section. The reverb is taking something away from it for me on the vox and piano.
First off, I don't have much experience with this type of Jazz but I think the recording is excellent. I can't see any improvements necessary to overall technical recording. Your vocal is clear and well recorded, the reverb sounds spot on to my ears. I really like the tone of piano. Because of my lack of experience with type of song, I kept wanting the vocal to go to a more melodic place but that's just taste. Great job!!
It's such a nice surprise to hear something so wonderful in this section. Don't change a thing. The reverb is lush but it works perfectly for the ambiance. Brings to mind Imogen Heap (one of the highest compliments I could give). Let me know when the album comes out, you've got a fan.
