My first apple, I ask not to judge strictly, a beginner in this business.
It looks more like a tomato to me.
The shape is too flat, the highlight is missing, and the texture is too homogeneous.
Just google "apple fruit image" and compare.
Welcom to PJ by the way :)
I still work over it, itself understand I recently has started to be engaged in this business, it is literally one month ago.
It's not bad I think.
Perhaps a little work on the banding would serve it well.
Is this really supposed to be in the challenge?
