I think this turned out well, and I also like Judy's idea of capturing light through the jar. I actually think you do some great still lifes when you set up your flower shots.

I've struggled with setting up still lifes, as well. I don't know of a course, but I've found that lots of experimentation is key, as well as really trying to capture the light in interesting ways. So, perhaps, with these same objects, you might try arranging them so that the light from a window comes through the jar. Another thing that has helped me has been to look at lots of still lifes photographed by others and try to figure out what they did and what I like or don't like about those shots.

look delicious, great colors... how about arranging them as is, but on a counter top and shoot flush with the counter top

Nicely done! I like the DOF and all the textures. And the beautiful orange carrots, of course!

I shoot still life the majority of the time. Personally, I think creativity is the key. You've managed to set this one up pretty well!

NIce idea to show the canned and the fresh. I'm no good at still lifes so can't help you.
