The design really looks good. Nice job. I have been to Deadwood and you successfully captured the flavor of the town.
There are a couple of issues that did grab my attention.
1. People think of Deadwood as a western town with a typical wild west cowboy history. The percussion cap revolvers in the logo do match that, but the more modern short barrel revolvers used in the right column do not. That is not a western-style firearm. I think it would look more authentic if you used a western style revolver for the headers in the right column.
A Colt Single Action Army revolver, also known as the Colt Peacemaker, was probably one of the most popular western firearms in the late 1800s and early 1900s. It was used by Buffalo Bill Cody and many popular western heroes. You will find lots of images and articles about that firearm on the web. A good image of the Colt with wooden grips will fit your theme very nicely.
2. It is never a good idea to post entire articles on the home page. You are creating duplicate content that will delay the ranking of the post page. Use excerpts on the home page, just like you are properly doing on the category pages.
3. The cartoonish image in the Deadwood real estate article does not match the western theme.
I wish I had your design skills.
