The new store looks awesome, but!...
What I miss from the previous look is how you only needed a quick glance in the featured tab to know what was available, currently you need to scroll down to see everything. I tried resizing the window, however it doesn't affect the size of the store "window" only the client.
So just a small sugestion that I think would make a big change, if the icons/skin arts size are a bit reduced in size so they can all fit or allow us to resize the store window, I think the featured tab would look much better.
I added a sample picture so you guys get the idea, sorry for the bad editing I only know how to use paint.
