How is this camera, for amateur photography?

I have a Nikon D-3000.
What's your opinions on it?
Hers some of the many i've taken with it.

It is an entry-level DSLR. It's ideal for amateur photography, especially with the built-in guide mode.

Have you tried taking your camera off of the auto mode? It's surprisingly easy to shoot in manual mode if you use the built-in light meter to help you set your aperture and shutter speed. The camera doesn't always choose the best settings for a shot, so you can often get better-exposed pictures if you pick them yourself.

Here are links to a few sites with tutorials that can help amateur photographers improve their skills:
