Below is the original, called Triangle Boy, (colors not really quite this bright; I overdid the photoshop adjustment). At the time (1980) I had just gotten a lot of new acrylic paint colors and was experimenting with them and also with using masking tape to create straight lines. This is done from a 4 hour class, with some rest periods for the model.
The faint lines are charcole plans to alter the painting, after I became dissatisfied with the original. There were several intermediate versions which I am not showing.

Finally, what if I were to add a banana, or would that be just too much ?
Below I have put in a banana digitally (taken from a photo I posed, then pasted on top of the real painting in photoshop.)
I'd also considered a melted watch, melted over the edge of the table, but of course it would have to be a digital watch. I also considered a glass of red wine, fallen to the table and spilling down the side, but I am not good enough with glass. So the final thought is the banana. But since the staring eyes look as if the guy might be dead, would a banana be thought to indicate why he died ? No, that's not something I want to say. But that banana certainly would go so well with other elements in the composition.
