Hey Jack,
Visited Concept 2 days ago and saw the changes and for the most part liked it alot. The navigation is alot better, and the layout looks great in the wordpress format. The banner with concept skateboarding blends in really well and makes everything more smooth and professional.
Now it's time for my complaints

, The first thing that caught my eye when i visited it was the blue background. Personally it's very distracting and doesn't blend as well as a darker color would. I have weird tastes with design so some opinions may vary.
I also noticed that the sildeshow type deal haha doesn't show pictures (using firefox if that makes a difference), but other then that it seems to work fine.
Your ad placement is good as it did not distract me whatsoever and I like the horizontal ads below slideshow

. If you were thinking of making your money off of adsense then you maybe should put a bit more in there, but I am known to crowd my websites with ads haha.
I think concept skateboarding is a
great website for anyone wanting to look a specific company videos and if i was personally into skateboarding i would be on there alot. I know it's stuggling to get started but that's because your getting into a tough niche. If you want I could email all of my members on my forum with a description to your website and a link to your subscribe feed.
