This doesn't strike me as a very strong expression of the challenge theme of still life. I also think the composition might be more appealing from a different angle.
I gave this photo a 1 because it didn't seem to me to fulfill my expectation of a "still life," a classic form of artfully arranged objects. Call me narrow minded but that's the way I see it.
A still life generally brings together a number of elements arranged by the artist into an eyecatching grouping. Ignoring that and considering the photo, it's an interesting subject but could be made more striking by increasing contrast. I'd suggest cropping tighter left, both to remove the extraneous bush and to bring the subject out of center, giving more illusion of flight toward the edge of the frame. Maybe check out info on the rule of thirds. Hope this helps :)
