It is very difficult to say something of substance using only one of anything - key, chord, phrase, rhythm, speed - or so I have found. I coined the personal term "principle of two" for this notion in my own improvisation. It's just a feeling I have that any art, not just music, seems to require a juxtaposition of at least two "things", more or less contrasted in effect.
I am an outsider pianist, with little formal tuition at all, especially not in any sort of theory, so this is a personal and intuitive observation which may be ignored. Nonetheless, I am inclined to agree with awesome in this case, and became desirous of your plopping in something, anything, different.
You obviously have a good feeling for romantic phrasing though, so don't stop that.
Maybe it would be better to post this in the improvisations section, as more people will probably find it there.
