First, I apologize for my delayed response
snoball, thanks. My goal was individual shapes, the different colors and markings, and shading.
Classic, thank you. I thought these pears worked well to, there’s so much to them. My paper here was 140lb Strathmore, It’s my inexperience showing, not the paper quality, I think. These paints are Pentel tube paints that were dried.
“... the colors become darker and less saturated in the shadows. This would be perhaps easier to make with some simpler geometric solids like cubes, than with curved surfaces and their gradual effects.”
That’s a good way to say it. I didn’t do so well either, did I.

Maybe next time.
Kay, thanks. You’re right, I did lose the white, or it’s so small it’s negligible. I think I tried to use yellow as the lightest. And I’m STILL afraid of the dark! I will be more aware. I agree, the shadows need to be darker—as classic said, less saturated.
Thanks.
