I'd recommend making the picture in the top left bigger. I believe you can go to 180x540
Looks nice, however I suggest trying an Iframe for them to land on...if you would like to see our I frame, check it out here:
Most developers know how to make one or if your interested in getting services from the guy that developed ours just let m me know, he works all over the world and through skype for meetings as well! Great guy!
We just launched our Social Campaigns product this week. You might want to compare that to the iframe approach?
This post will get you started:
I would also consider adjusting your logo as currently it is hard to read the writing within it. Regarding a Facebook landing page, we had used an iFrame app before using the new Social Campaigns product from Constant Contact. We found Constant Contact's new product much easier to use and very flexible. (No coding skill required!) Check out our Facebook page https://www.facebook.com/DudleyandNunez to see an example of a larger logo on the left as well as the Social Campaigns product in action.
I would also suggest increasing the size of your main image and developing a landing page that let's potential fans know exactly what your page is about and how they can benefit from joining your group.
I would like to see a bit more personality on your wall - it's nice to post links and share information, but I would want to "hear the voice" and see more of a presence of the Savannah Striders on the wall.
