I am fairly new to photography.
I have a Canon PowerShot S2IS and I need help.
I am a polymer clay artist and need to take pictures of my work for a mini-catalog.
I am attaching 2 pictures that I have taken previously.
Any help or advice you could give me to make them and future pictures better would be greatly apprectiated. All my ornaments are no bigger than 4 inches and average about 2 inches.
This one is really bad.

This one is better, but still not great.
More examples can be seen on my picasa website in my sig.
Thanks!
PS - Remember I'm a beginner - so be specific.
