There's something "off" and flat about them, (and they're really noisy but I guess you can't help that)
White balance is dodgy too. Tthose white plates should be white.
The main thing is:
a) hold the camera straight. And if you INSIST on tilting, at least make it deliberate. Those slightly tilted photos look terrible and careless. Photo 1 is a good example - looks like everything is sliding to the right.
b) Watch your backgrounds... photo 7 is a good example. Subject is that bowl of food, but there's half a bowl of something else sticking in the frame. It wouldn't take much effort to clear up the background, or move your camera position to frame the subject better.
c) focus. Sure, small DOF and lots of bokeh is nice, but sometimes it's distracting too. Small DOF is just a tool to draw your attention towards something and away from everyone else. 6 is a good example of where you have used this tool badly. A HUGE out-of-focus brown thing at the front takes up most of the image, and your attention wanders to a green bean and a mushroom stalk.. not exactly exciting and it doesn't make for a good picture.
Hope that was useful. The main point is *THINK* before you click. What is the subject? Why am I showing it? Is the subject clear (i.e. background and foreground)? Where do I want the viewer to look? What do I want in/out of focus?
