Excellent looking theme but then I wouldn't expect anything less from Russ & Steve.
I'm liking the category images fl0ated the right. Not sure your aware but you are able to have different images floated to the right per category within the .categoryStrip. I wasn't sure whether you were aware but thought I'd mention it on the chance that was something you might want to do.
The nodetitles within the nodelist I think you should change from that default XF blue (probably last post also) perhaps in something more fitting, personally i think a dark red coloured font would look nice but that would be preference on my part.
Overall, great look theme and really good domain name.
