ntheni,
my comments as follows :
Certain photos are over exposed; especially the rice.
Majority of the photo contains yellow cast and some green cast (especially the pudding).
I have edited a few photos to show you the differences once the color casts are removed,
I have also increased the contrast, boost up the color and sharpen a little bit to make the photo looks more appealing.
Keep up with the shooting and improve your photoshop PP skills and you will be there one day... (;p to be honest, I hardly taken any food photography :bsmilie
