There's something wrong with your gallery. When clicking on one of the thumbnails, the picture is very pixelated (it's the enlarged thumbnail, in fact, instead of the higher resolution picture). Looking at the thumbnails it seems you have not postproduced your images, probably took the JPEG outputs as they came out of the SD card. Many pics are too dark, as the R-D1(s) meter does underxpose a little, to prevent blown highlights. This means you have to edit the RAW files in the RAW converter to get the full quality of your pictures, or, if shooting in JPEG mode only, to overexpose manually in certain, especially contrasty, situations. Needs some experience. The R-D1 is definitely not a point&shoot camera.
Another thing I see is your framing - does not look very experienced. Ira's right by describing your style as "point at random and press the shutter" - it really looks like, sorry. You must work hard on that. And many of your pictures, let me mention Speeding Vespa, Bird, Trolley, Dog Walking Shadows, and others, should not have reached a public gallery ever. They have absolutely no visible quality for me.
I too shoot a lot of crap, but then at least I trash it after the first veiwing on the computer (I never delete on the card). To conclude, it's better to post one good pic than 100 mediocres.
Good luck with your further shooting experiences, and i hope you have nevertheless fun with your R-D1
