Hi guys, first off I really love the idea of this background. But because of the strong perspective being scrollable to the left and right could be a problem. So I attached two of those backgrounds together, so that my client could see how it looks as whole. Because you only see always a small part of the background only it shouldn't be a problem. So we went with it.
