I think some of your points could have been more specific. You can try to make it more personal, and highlight some of the characteristics that make Rice REALLY stand out. For example,
"Its high undergraduate student-to-faculty ratio and median class size ensure personal teaching and learning, in that each student can join the discussion and get the opportunity of face-to-face talking with professors in class."
"In addition, campus life in Rice is very joyful"
"High level of accommodation can make me very comfortable"
these don't really make Rice seem to "have a different point of view from other universities" as you wrote, because those descriptions can fit most LACs. Avoid general (and empty) words like "joyful". The approach is good but elaborate more about the distinctions, things that make Rice special for you. Your last point about Houston is good.
I may be a little harsh, and I'm not that good of a writer anyway, so consider my suggestions but don't take them too seriously, I could be wrong :D
