They're typical shots, I guess. Digital nature photography is very boring and amateur in most cases, so I'd suggest staying away from it.
These pictures look like they were taken in the automatic mode, with a typical set depth of field, etc. That being said, try learning the manual mode. You'll find it difficult at first, but the rewards are greater in the end. Make sure you're shooting in Camera RAW, so that the photos can be adjusted the best if need be.
Yeah, not sure what else to say other than keep going.
Yeah, I guess they are pretty typical. And yes, I was using the Auto mode, only because I just got the camera and was too impatient to learn how to use the other modes. I do use a lot of the Aperture and Shutter Speed modes now, though.
Juju - Yeah, I've taken a few, but most of them are just mess around photos, messing with aperture, exposure and things like that. None good enough to post though.
T.E.I. - Yeah, I would've gotten the D60, but this is my first ever real DSLR camera so it's fine for me haha.
