It must be your monitor. I have a 24" iMac.I dont know if its just my computer monitor, but all the photos seem to be to cool. Are you useing an auto white balance? Try putting the white balance in "flash" or even "cloudy" mode to see it you can warm the photos up a little. . .
Your shots look so crisp and clean and wonderfully composed. Just what I want to see in commercial food photography. I think it is really neat how you are the chef & photographer. Very talented. Keep up the great work.
