A few things that I hear: I feel like your bass frequency is muddy, and I feel like the difference in the amount of processing on the acoustic vs the voice is too stark. I love the resolution of the bridge, but for the bulk of the bridge, i felt like your vocals were tucked too far back. I see what you were going for, but I think if you just maybe brought the vocal verb up on the bridge, it might add enough pop to blend with the violins a touch more. Happy mixing!
