The images need a bit of photoshopping and cleaning up or resourcing.
The case pic has an ugly cut-off reflection underneath and jpeg artefacts.
The circular logo/badge has a band of lighter pixels around the rim that make the edge over the dropshadow look messy.
The boingball in the bg looks vertically squashed too.
Also, the case pic might look better on the left side so it leads the eye in instead of out.
Otherwise, quite nice.
