I almost did not comment on this painting and then thought how I would feel if no one said anything and decided to suggest the following:
A light source would help this painting, as it is there is no light source, the vase should have a larger shadow if the light is directly above the flowers.
The books are not lieing flat on the table and either the binders should be darker or the covers lighter as they both would not be the same color value.
The picture on the wall should be completely dropped as it competes with the subject matter for attention.
A darker background and lighter table top would push the wall back and bring the focus point forward.
Your composition is good and flowers are belivable, keep working as you have prosmise.
Well, I like it a lot. In the contrary to encourage you to go to something more realistic, I will encourage you to to use bolder brush stroke and less details. This make me thing of a Matisse.
Eubie, this reminds me a little bit of Van Goethe. Ron is right about the picture in the background. Not only does it compete with your flowers, the horizon line is on a diagonal.
thanks for comments, did you see the one where I made some changes?
Eubie, the one I am looking at doesn't mention any changes. Let me know where that is if this isn't it.
