In my view you have compared it to the only other language for which it is small by comparison :) But different strokes for different folks! I have nothing against Scala, its multi-paradigm thing is cool and impressive, it just isn't for me except by way of curiosity.
I think all the links in the first two sections in the What Is Scala[0] docs give the flavor pretty well. It contains a full (and not small) set of OO language functionality, alongside an even more full-featured functional language.
There are a lot of adjectives you can use to describe Scala - mostly good ones! - but "small" just isn't one of them.
