Easy, extremely easy, just SIGN UP, THIS SITE IS 100% free, just register, again it's free, once you register, LOG IN, and you'll be able to see the many concept art sections that populate this forum, and full of RARE and EXTREMELY RARE artworks, screenshots and images, EVERYTHING OFFICIAL, released by capcom.
As I said, I'm a member at capcom's press, so I have access to all the official artworks they release for journalists and experts, so all the images and stuff you'll find here, is extremely hard to find elsewhere.
hope you enjoy your stay here, we're all friends, and very kind with each other, so feel free to express yourself whenever you want
