Generally I'm a bit more interested in get to know a little about the photos. Can you tell me how you achieve the shots? Was is shot from the floor and up, or from above?
I havent got much to say about them, im sorry, but I can give you a little hint about stock photography. The key to nearly 90% of all stock photos, is that they are well lit. I mainly see stock photos as very bright and some kind of "hard-to-achieve" exposed.
When looking at your three photos, Im a bit worried for if the two first is exposed enough. The last one is a bit brighter than the others - which is a nice thing.
So maybe try to crank up the illumination on the two first photos a bit.
That being said, I think you did a great job cropping the photos as they are! That fit stock photography very well.
And ofcause nice to see you used new and fresh food!!
(Seriously; I once saw a stock photography of an apple, where it was obvious that it wasn't fresh! Thats simply not good enough - unless its a part of the idea behind the whole creation)
