What is the value of this Antique Chinese watercolour?

This is what I & my friends think: The 2 bigger characters on the right (top & down) are 虎嘯 Tiger Roaring. The two smaller characters on the left are the name of the person ( which repeats inside the red stamp).
The name may be 金山 (gold mountain). It was bought at Wuhan Antique Shop in China
