Very nice - I like the fill-the-frame-aspect of this one. Just tomatoes and nothing but those. It should be "made eternal" in the Photo Themes. There is a Theme thread out on "The Colour Red" (or some simillar title) somewhere - probably hidden wey down in the "vaults" of the Themes, but it is there. This one would fit the theme perfectly!
If you really are a beginner, you are off to a wonderful start. The composition is great...just be mindful about too much color saturation. It's easy to do in digital work and can be distracting. You have it under control here, and it's a great picture!
