You wanted me to write you a critique for this one. To begin with; don't mind the stars, they aren't informative at all.
Photographically: I see that you used a pocketcamera for this one, this will make it a little more difficult for me to help you with what could have been done to change the metadata. The idea is that you would want a smaller aperture, somthing like f8-11, this would give you much more details due to the increase of depth of field. This would result in a slowershutterspeed, but should be well within the limits of a handheld shot. (You could try landscape mode, this should give you some depth of field in the image, if you can't change the above manually). Also it seems to me that the focus is a bit off. This gives you a blurry effect to the image. I take it that this was autofocus at play. Remeber that autofocus will seek highlights and contrasty areas when choosing where to place it's focus, so it's somewhat uncontralable. In this case I would recommend you to try several times to see if the focus is where you want it to be, even try to move a bit back from the glass, because you could also crop this later. I think this is the technical information I think I'll give to you, since you'll see a great improvement if you are able to change these things.
As for the camera, I'm sure it's a good one for your use, just remember to clean the lens from time to time. I can see that you have some smudges on the lens.
And when it comes to cleaning stuff, make sure your subject is squeeky clean as well before shooting it. No one really wants to see a dirty subject unless it's intentionally.
Post-processing: I'm not familar with Microsofts Photo Viewer, so I can really help you much there, but I would add som contrast to this image and a little saturation to make the colors pop a little more. There are some good free photoeditors online as well, like Picasa and Photoscape - have a look at those two and you'll be happy with the things you're able to do to an image after capturing it.
All in all it's clear to everyone what you're trying to show them, so you've got a simplistic and nice image here. Experiment more with the different settings in your camera, it's imperative to know your cameras pros and cons to be able to understand when to use what to achieve the best possible result
