Above is the texture I attempted to create for the second part of the lab. This was definitely the harder part of the lab, and I think were I too do it over, I would look for a better source image, as this texture still bears the marks of its initial offset.
Furthermore, when I used the pattern again, these issues were amplified, where I thought I had made the hard edges difficult to discern in the above file, the fill bellow looks very much like an artificially developed texture.
