Top faces are brighter now and soft border added for easy distinction. Shadows on either size should be fine.
I've edited the 256x256 to show some further suggestions. I tweaked the gradients, the blurriness and the shadow. It might be perhaps worth to also tweak a bit with the perspective (the top face does not seem 100% correct to me). See the attachments for reference.
