A Banner Dilemma

I have been trying to come up with a new banner for my store. Not that I don't like the old one, but I feel like I need something fresher that will suit the way I photograph my mice now.

Here's what i came up with so far....



I added a border because the banner will be white on white and I wondered if it looks better with a border for the mouse to be peeking over. Of course I could do the first one with a border too... I'm undecided... what do you think?
