I second the watermark comment! I understand not wanting someone to steal your images but there are ways to go about it without being that "in your face". Especially in the first one, with that placement, I could delete the watermark in under a minute...so it doesn't really help to make it that big.
...okay, I'll step off my soap box!
I like the first one the best. The second one is a little flat, and if it's going to be centered, I would want it to be perfectly centered. The handle throws it off a little.
