Photo of the day - Grapefruit fun

This one came out of some playing around with a cheap lens add-on for my iPhone, you know, one of them 3-in-1 jobs. It's no Oloclip, it only just fit my iphone but I was really surprised with what I could get with it.

I used the macro lens for this and edited in VSCOcam app. Love the level of detail but the photo could probably benefit from some more contrast in the post processing. What do you think?
