Thank you all for your feedback!
Funny how we all have different opinions as to which one we like better.
It looks like number 3 and 4 are getting a bit more votes... although on such a small sample size, it's probably meaningless...
I like the 1st one the most, followed by the 2nd one.
To me, the perfect one would be the 1st with the swan of the 2nd
I was hoping there would be a clear cut winner, because I'd like to put only one of these on my site, but I don't know which one!
Anyway, thanks again
