Lovely!

thanks

Good job! I don't think the shadows look too bad on this. I enjoyed the process video.
I think the colors work well with the shadow. But when I desaturated the image in a photo editing program the actual values are not shifting much across the image. So the light side is not light enough, and the dark side is not dark enough.
The shadow effect is strenghtened by such things as color temperature, but a key component is to have your light side a lighter value, and your dark side a darker value. The actual cast shadow, the part sticking out from the pot was noticeably darker.
Some of your shadow at the darkest part of the pot itself should approach that in value. And then on the light side it should be lighter in value.
One way to do this is to start with a mid tone. Then for your shadow go a bit more saturated, and lower in the triangle so that the values are getting stronger.
Then for your light tone do the opposite, going slightly less saturated (strong light tends to bleach out color), and slide up the triangle to a lighter value.
If you want to involve color temperature in that you can slide more to the blue for shadows, and more to the yellow for light, if you are dealing with a warm light.
Sometimes it helps to start with a background that is a mid tone also so that you have to go lighter and darker for shadow and light.
Also, I enjoy the 2dsXL! That is what I did a lot of my paintings on. But I have been working more with my phone since I have it with me now.
