The skin looks awesome, sharp. But firstly, the header point is totally on spot. You need to make real flashy logo for your arcade, it looks pretty much static with the slogan misplaced as well.
I love the placement of your AdSense.
One thing you need as well is a favicon that is unique to you. People will remember you.
That's all I can think of for now, all in all awesome job, but I suggest working on a more classy logo.
Good luck.
