here are some things that "I" (like "I" count) think would improve your shot...a black background...would make your leaf standout more...as it is, it just totally blends with the background. And that would make your pin standout more as well...JMO
The tones in the dead leaf are repeated in the background patterns although they are more linear and constant and the leaf textures still contrast nicely. The white pin is the last remaining link before well deserved oblivion and then renewal.
