If you want feedback and ideas, how about joining the sailcut-users list or the saildesign list?
Otherwise, you could post the design here, but it looks like not even the hardcore racers who frequent catsailor want to comment on designs. Strange, but that is my experience so far.

Plotting 1:1 templates before transfering the design to the cloth sounds like a lot of work. Perhaps it's OK for a jib, but for a radial mainsail.. Whew..
With the "new" cloths designed for laminate crosscut construction, hand plotting is good enough and quite fast in my experience. But for spis you need to team up with somebody who have a large scale CNC cutter as the cloth need to be laid out in a tri-radial cut.
