ID the Artists signature I have two watercolours (Birds &amp; flowers blossom) but have not been able to find anything regarding who painted them.
It looks like 怀谷 , from the idiom 虚怀若谷

虛懷若谷 means: 


  have a mind as open as a valley -- very modest; be extremely open-minded; be in a receptive mood; be open to conviction; free from pride and prejudices; from a sense of one's inadequacy; modest and open-minded
