|I feel like it's too monotonous. Obviously that's the color of the flower, but being a bright yellow flower, even though it's dying, with the even light doesn't give a "death" kind of vibe.
Visually, the shapes and composition are OK but just OK. Not too pleasing to my eye personally. The technical aren't bad although the small reflection to the right seems to remove it even more from the "death" theme, by making it obvious that the flower is on a shiny surface.
I think had it been on some dirt, maybe with some harder light or some grungy processing, it might have done better.
Plus, I don't think a lot of people will associate wilting flowers very closely with death, even if it's a very literal portrayal of death.
