To be a real photographer you must buy lots of expensive equipment.
Never mind if you actually use it or not, or just put it on the shelf for show.
We all know that buying the latest and greatest camera makes it take wonderful pictures, the advertisements say it so it must be true!!
Seriously, I think you have a good eye. You may want to consider crossing over into SLR land to open up more creative potential, but it may make all your lights look cheap.
I liked your moon shot. I would consider two exposures for that, a long one for the background (blow out the moon) and a short one for the moon, then combine both in Photoshop to take care of the dynamic range. Hey.. it's art.. it's not journalism where you can't PhotoChop anything
