Check your camera settings. My guess is that you are too close and haven't switched on the macro setting (if you have one) Either switch on the macro setting or take the camera a bit further back so it can focus properly. Otherwise try supporting your hands while taking the photograph or use a tripod to prevent shaking. Sven
Alot of the other stuff you posted looks quite promising, but you will not get a representative score with a blurry picture. Everyone will vote it low scores. A clear, well lit, well focused picture will always fetch higher scores.
