If there is no light, we are not able to see any shape, value or color. So, no matter what the subject is, we just painting the light.
I put the still life under the "portrait light", than painted it as a portrait painting, and if I put them under the nature light, I think I can paint it as a landscape painting (I will do it later once I get a stabled nature light). So I think the subject should not be a matter for an artist, the matter is how to see the subject in the light environment.
Please email me if you are interested in this one.
