Before you thinking about making black and white painting or any idea you have at first which sometimes limit you by " should be" "suppose to be " " must be " will control you to make painting with hesitating, so just don't think about too much what you impress it and paint it.

Your favor subject " tree " which important have own interested subject which you can commit your expression to find variation of your expression, tree above the ground and under the ground which shows mechanism of nature and earth so you have concept, and just finish it.
