Beautiful job!! These models are great but I think it's time to start removing these huge dotted fold lines. Just a point and instructions on where to be with points as references. Heck, a lot of thee parts should be separate panels and glued, then there won't be any lines. Very light lines are sufficient, or a very lightly colored line, or no line at all would make a better and more realistic model.
Of course, anyone downloading these models could do that and the fact that they are free is wondrous in itself!
