I think you site looks great. I like the theme of the site, construction/industrial/skater, not sure if that was the look you are going for, but that is what I got out of it.
Great header too, the people all standing around holding the yellow bags. I think your site is straight to the point and when I looked at it I knew exactly what you were selling.
This may be something for you too look into if you are interested. I really think your bags would be big in Japan, I travel to Japan on a regular basis and am always seeing the new trends and this looks like something that would fit in without question. This store, Rescue Squad, is big in Japan, your bags remind me of some of the items they had when I was there last October. Here`s a link to the online store. http://rescue99.com/
Just an idea if you ever thought about expanding. Good Luck!!!
