This is a really cool mod!
Idea: I'm not sure how/where you got your food images, but I notice they have poor multi-sampling and white around the edges. You can get better multisampling when shrinking the image in an advanced photo editor like Photoshop or GIMP (GIMP is free). Also, if you add an alpha channel and use the magic wand tool to remove the white background, the edges will be feathered in the alpha channel rather than in white. And finally, if you get bright images from photo catalogues, they will look better in-game when reduced to about half luminosity.
