Nice clean mix on And I Wonder.
I kept wanting to hear two things. The first was something to break up the rhythm guitar a little, whether with another rhythm instrument added, or something else to make the strumming sound less predictable. It is rhythmically consistent (which is my big bugaboo - variable time signature syndrome). Maybe even something like a little more reverb. The other thing is the vocal eq seems on the high side. A little boost around 1K on the player brought out a bit meatier sound. I want to feel the dynamics as well as hear them.
One trick that was suggested to me is to make a clone of the vocal track, maybe use a different effect, run the volume envelopes a little differently and pan it differently from the original track, and then run them together in the mix.
