Jamie, I think that's a definite improvement. Nice work. The smaller logo puts the main content in a more prominent position, and the "Sign Up" button looks better.
It looks like you've done a good job with SEO too, with keywords in all the right places.
Some minor additional points:
1. I might be tempted to use a different font for your headings ("Where the big dogs meet!!", "Advertise with BigDogCattle.com" etc) - maybe a sans-serif such as Helvetica/Arial or Verdana. Currently the text looks a bit "samey" all in Times.
2. Your form fields on
http://bigdogcattle.com/contact_us.html are quite narrow - I'd recommend doubling their width.
3. Some of the elements are broken on your "blog" page:
http://bigdogcattle.com/blog/ - "General Calf Club Blog", the "Search" box, and "November 2009", in the left hand column. (At least on Firefox and Safari - haven't checked in IE.) You can't click them or select them at all. I
suspect it's a CSS issue. If I have time I'll post a fix after the weekend. Meanwhile you could try running your pages through
http://validator.w3.org/ and fixing the errors - that might solve the problem.
Otherwise, looking good!
Cheers,
Matt
