In my opinion this logo works very well.  I enjoy how they included the word within the imagery is great.  Using the f's as steam was a great solution, instead of just including the word under or on the side of the logo. That was something I had struggled with when I was creating my logo. I also think the extra swirl on the C to separate it from the e's makes sense but I am not sure it works. I feel less swirl might have worked better. 

 

In this another good example of text and imagery put together. The curve of the enlarged capital  matches up very well with the image of the wave. This helps to create unity between the image and the text.
