I see you've changed it a bit! It is more legible now, I like how you moved the lizard & cockatoo, and made the fish more prominant. But I think the original art with the cityscape behind the pets and the bricks underneath them was more interesting. (It anchored them, now they look like they are floating in space.) Also, keep only one of the fish bowls, (the larger image works better, but placed where the smaller one is-- the puppies look like they are looking right at the flying fish, cute!)) and I agree, the rodent & turtle need to be more to scale with the other animals.
Looks like it will be interesting - is this an on-line magazine, or print?
