Very noisy, made particularly visible by the chroma noise, underexposed, and there doesn't seem to be anything particularly interesting about the subject. I recommend picking up Noise Ninja and bracketing your shots, standing closer, or getting a better flash.
I think that using a lower ISO would obviously help the graniness aspect of this shot. I do think a different angle would have worked better, but I know the batteries ran out. :(
It also might have been cool to take a shot from ground level looking up.
There is a lot of pixelation in this photo. The focus on the bike seems nice and clear, but I wish that the whole thing was in the shot, instead of being cropped off at the bottom.
