Here are some test shots I got today out running around downtown...Please feel free to critique.
These are very good for a beginner - you have "the eye". Please remember that a lot of very technical and rule-oriented people are attracted to photography. I have often seen exactly the good and interesting things about images harshly critiqued, just because they don't follow some "rule". So always accept critique as another person's opinion and let your own judgement be final.
I see some JPEG artifacts around the top left of the statue. They might have come from the camera or postprocessing. If you are shooting JPEG in the camera, make sure you have "quality" set to high - this is independent of the number of pixels IIRC. With modern computers/networks/cards it isn't worth the tradeoff to shoot highly compressed JPEG.
I would have increased the exposure slightly to emphasise the flowers in the window rather than the sky. That would also bring out more detail in the wooden beams. (It's possible that's actually what you see on your monitor - most are set to run too bright. I am looking at this on a calibrated monitor.)
** Your equipment is completely suitable for a beginner, and in fact the big 100% finder and good outer autofocus points will make learning easier. Your logic in choosing it makes perfect sense to me, even though you didn't ask for my or anyone else's opinion on it. I would probably have ended up with the same camera for slightly different reasons.
