Kallisti.... Suggestions to consider...... Y'know what I'm thinking would make the image even more interesting and striking? Put a bright blue or green or yellow or some other color cloth over the stool, something which offers a vivid contrast to the orange -- just as it's important to have contrast in B&W it's also important when shooting in color. To me, the blah brown top of the stool adds no interest to the current image and actually almost detracts from the orange. A bright blue cloth or bright yellow cloth along with that orange would make the whole image much more dynamic and eye-catching. Or drape a black cloth over the stool and stick the orange on a brightly colored plate or in a bowl for that punch of color and contrast. And, yes, you would still learn from your experiments with lighting, too. Shadow on the orange and on the stool top looks good, I like that.
