I choose a painting to write about and I am having the hardest time trying to see the form, color, space and much more. Is there anyone that knows this kind of stuff?

First, you need to choose a painting. Then you can do some research on the painters style. Often there is an analysis of a painting, that you can get information from. Also, look up use of color, use of space, use of form ( in art); Google can help with all of these.

When you have chosen the painting you want to explore, repost with problem areas and we will try to help you.
