Sorry to bug everyone again.

I was going strong until about 4:15.

What I had been doing up until that point was moving control points around on the lofted curves. This was updating the surface so that my projections matched up nicely.

Then I tried to add another projection + trim and this happened (see attached image).

As you can see there is some weird artifacts being generated, and I'm not getting the trim as desired. I'm pretty sure this is due to me pulling the control curves in ways I wasn't supposed to. However, I can see BLYESS doing this as well (although not nearly as much). I also went back to using a loft with loose, as this seemed to be the option tat was used for the tutorial (see around 2:21).

Sorry to impose like this, but could someone take a look an recommend what I need to do (even if it's another tutorial to improve my skills)?
