Interesting. Looks like all the finished paintings are very similar to me. I suspect types of underpainting is more a matter of personal preference than a definite requirement for a certain look.
I cant see a difference on my phone. The one thing I would add to the topic is that if you plan to utilze under base painting in the finnished product then keep under painting in transition. Other wise peices of under painting of static color randomly showing up will flatten the illusion of space.
I like these studies, but I think you would have had to allow some of the under painting to show through in certain areas to give it some depth.Love the blue mug on the red book. The crease in the orange is a nice detail.
The plain white canvas was pretty bad. The white would come through too much a ruin the values. The toned canvas was pretty good but had some trouble under the lighter values. I am still deciding among the rest.
