I have to say it looks good to me! Has a nice clean almost air-brushed 
feel that distinguishes it from other images.

Though if you want the lighting to look more interesting, at the cost of 
looking more conventional, maybe stick a highlight light in there, i.e. 
one behind all the objects at a shallow angle so it adds some 
rim-lighting, particularly effective if you have some specular on the 
objects.

But I'd say just work on the details of the scene, I like the lighting.
