The main entrance of my living room faces east. Will it have any influence on Feng Shui if I hang the painting of flowing water and wealth on the west wall?

The painting of flowing water bringing wealth is very suitable to be hung in the living room and will not have any feng shui influence. It means that wealth is like flowing water. However, in many landscape paintings, water must flow inward, because water generates wealth, and only when water flows inward can wealth be generated. If you believe in Feng Shui very much, it is best to ask a Feng Shui master to come to your home and figure out where your Feng Shui wealth position is and where the painting is suitable.
