take a look around stock agencies, not that I don�t like your pics, some are pretty nice but not stock oriented.. navegate a little on an agency and you will see what would be suitable for stock buyers..

picture two has hello kitty (trademark) but even without it, it is too artsy to stock

you need to think stock, would these sell? look at stock sites and see if stock is really your type of photography and if you are willing to pursue it

Lisa thanks for making me feel less Russian

I am not Russian its a private joke.. While ago on a topic a person said that didn�t understood my comment.. so I told him I was Russian

now other people critique sorry for OT

agree with above plus they look flat in the mid tones

Thanks everyone
its really helpful knowing what I have to change, hopefully Ill get new photos accepted

The only thing I'd add to the comments you already received is that you need to think about getting your images to sell, not just getting them accepted. By and large, well lit and more upbeat/cheerful/sunny images sell better than dark/brooding/gloomy.

 Most of the time, the simpler the composition the better - so, not just that your waffles are cut off on the sides, but the surface on which they sit is distracting and there's some cup in the background, also a distraction.
