It's a brush set by PSDtuts.com, but you need to signup and pay to become a 'lus' member to get the brush set. They have quite a few other sets though, so it's actually worth it. But make sure to cancel the subscription after you download all their resources.. I made the mistake of letting the subscription continue for like 4 months.. Haha.
Looks like a very nice, solid design. One crit thought is the "This shit belongs to Dalton Hurd" comment in the footer. I hope you don't intend on using that in the final design. While it made me smile, the swearing is very unprofessional.
