Nice idea, but you need to be more careful when you focus, you have focused on the background rather than the apple.

You might just be too close for what your camera can cope with.

what are you working with?? - most lenses have a minimum focal distance which you can find on the lens itself which will help

If you're using a compact then are you using the marco setting? - or try pressing the shutter half way, which will lock the focus, then you can move the camera to what you want to focus on....

Your answer might also depend on what type of camera you're using. Mine forexample, has settings to where you can make it focus. If it's a DSLR it would also be a good excuse to practice manual focusing.

Judging by the quality, i'd say it's not a DSLR. It's a compact, or a cell phone camera. Either way, i think you got to close to that apple core, beyond camera capabilities, i suggest moving a bit backward and try again, or activate macro setting if the camera have that.

Guessing by the comments - you replaced your entry with this one of avocados - I really like the avo pic & think its one of the best of the bunch. Well done.

Its a nice picture but the problem is that the votes that have been placed so far were placed for the apple picture not the avocado picture. The score will not be an accurate reflection of the picture as it is now.

beautiful work

Maybe increase contrast a little?
