Great job pixeling this apple. Oddly enough i ended up sketching this very same apple in photoshop not too long ago. In any case, great job.
Thank you for the nice comments. Here's a convincing post on pixelation in favour of them being genuine: http://www.wayofthepixel.net/pixelation/index.php?topic=5630.msg66818#msg66818
I pixelled my image, each individual pixel, from scratch by looking at the reference and using its colours. I didn't trace, colour reduce or paint over the original. However, I think now posting this kind of stuff is a bad idea. I've done another one (same method) of bananas and that's been removed from the gallery.
The two dark pixels on the upper left of the apple are odd...
Do you have a WIP?
