I just thought because the sewer has taken 1 week and I have been putting alot of effort into it. It actually is i think 105 x 105 blocks. So it is huge. Sorry if you didnt like it.

Yup, it definetly looks great for a sewer and the ammount of work must have been great, so kudos for that. However, you got to admit it's mainly a dull task to make it that huge... So don't get me wrong: I like it and it's design, but I don't think it would be enough for builder just by its own.
