Logo proposals for counsulting

I always find that making a choice about what is going to become the identity of their brand can appear a real challenge for clients.

I am trying to find the best way to present my work, explaining my designs without putting to much affect, describing each proposals for what they stand for and not focusing on wich one I would like them to choose.

One of this logo was chosen but a few days later after sending all the final files, my client called me. She was quite annoyed and couldn't figure why but the new image of her brand wasn't making sense anymore. I guess, it's all about feeling at the end, no matter how facts can be presented.
