Hi. Your vessel have two "pods", one on each side of the main hull. Those can be expanded so they take the functions of the upper part of the vessel that is too high (for the challenge). Unfortunately that will alter the overall look. I can try show you a picture in 6 hours or so if you want me to (I spawn it in and do a rough change, do not have the time now).
I ended up just starting a new build. The rough concept of this one was that triangular look, that when I started changing I really didn't like as much. :). I'll have something new up in the next day or two assuming it comes together.
