Ok, I can't see the pictures because here at work they block SkyDrive. But based on what others have said, and your statement that you've not really used a camera before, let me offer some advice.
First, the lower the light, the longer the exposure, all other things being kept the same. This means that the sensor is gathering light for a longer period of time, and during that time period, motion will result in blur. How noticeable that blur is depends on a few things, but mostly the focal length and the amount of motion. This means that the more zoomed in you are, the more noticeable the motion blur will be. What all this adds up to is that while holding still while taking any picture is important, in lower light it becomes far more so.
While the camera on the 928 has OIS - Optical Image Stabilization - it can't account for all motion. The way OIS works in most modern cameras is that the lens (or in some cases the sensor) is stabilized by a gyro, and moves in response to movement of the camera body/lens. So if I'm holding my camera with OIS (shown below), and I move to the left slightly, the lenses will adjust to the right, to keep the image that is projected onto the sensor stable.
The motion that can be compensated for by the gyros is small, so even using a $2500 (retail) lens, I have to hold very still while shooting. Likewise, you need to keep very still with the 928, while shooting in low light, because it can't compensate for much movement, either. The OIS is not geared so much as to compensate for body movement as it is to compensate for the very minor movements of muscle twitching and even the pulse caused by the beat of your heart. Yes, a heartbeat can cause motion blur, and a good photographer will time the shutter-squeeze between heartbeats if he can in the situation.
The OIS in the 928 is a bit different than what I have in my high-dollar lens. In the 928, instead of having gyros to compensate for movement by moving lenses, the entire camera assembly is mounted on very small springs. So my guess is that the 928 can compensate for even less motion than my big lens, but hey, you can't fit all that junk into a phone, now can you? Still, the principle is the same - if the phone camera moves to the left a bit, the mass of the camera/sensor assembly causes the springs to flex a bit to the right, thereby keeping the image projected to the sensor lined up.
So here's a question to ask yourself the next time you're trying to take a low-light image: Just how much can those tiny springs flex to keep the image lined up on the sensor?
Does this help? Oh - and if you would post your images to the forum instead or in addition to SkyDrive, more people will be able to see them. :wink:
