Barbara, Love the shapes and the lovely soft colors in the iris portrait. The tulips made me smile. Beautiful line work in the leaves and cool perspective on the flowers.
Thank you Larry, Doug, Robert for sharing your struggles. It has encouraged me.

For many years I have looked forward to having an 'empty nest' and spending more time painting and improving. These last months been so discouraging as I hit a physical wall and I adopted the mantra, "Work smarter, not harder" I hope that you do not mind that I keep you in my prayers.
For myself I have been thinking and reconfiguring my studio space and I think it is helping. I am able to paint longer without pain (YAY!)

Unfortunately I am frustrated by my painting.
Larry, you said: Yes...seems the BIGGEST most COMMON culprit to most work (90% of the time)...are issues with values.
Breaking main color groups into a dark, mid, and light value...and locking your attention to it is most critical to becoming a good proficient painter. Advancing from there are applying midtones.
(Sorry, I'm not sure how to show a repost. Will have to figure that one out) Main color groups? Do you mean masses, as in a mass of trees or a hill. Are mid tones different from mid values?
I am self taught and I am always looking for learning sources. Where can I find this information?
The following painting is what I have worked on for the past couple of weeks. It is a very different painting for me in that there is no direct sunlight and right now that is really bothering me. I've also altered a couple of details from real life in an effort to improve the painting, which I'm not used to doing and I'm not sure I've done a very good job of it. I see the foliage still needs work (It's amazing how seeing a painting on screen makes the errors pop up). After seeing Larry's comments on getting values down clearly I desaturated the photo and see a few more spots that need work. There is hope for it yet. Any other suggestions?
