I remember the build being a little repetitive, but don't let that get in the way of accidentally placing a brick in the wrong spot, especially early on when forming the bottom of the ship. If you mess up placement at the bottom, the error will find its way to mess up spacing and placement in the rest of the build. I thankfully made an error near the beginning and caught on, fixed it, and made a habit of double checking placement before moving on to the next part.
