I love the logo

. You did a great job keeping it able to scale down to lower resolutions and keeping with the theme. The "F" knocking out the "I" made me chuckle, partly because I did not notice it right away.
Some of your icons and buttons are still default and do not look right next to all the customized images.
With the image on the right the whole forum feels very crowded. A little extra spacing between the ads and the forums would help in this case.
You have a good amount of traffic with a large amount of content in relevant forums, great job
Overall the forum looks great. Getting some more customised graphics will really tie the site together.
