I color the cut edges with either marker pens or colour pencils, also where I can I use the back of my tweezers to push out the paper near the base of the flaps so the actual outer surfaces get closer together.
I plan to use this model or the female Blood Dragon .pdo file to create EVA foam armor for myself for Halloween/Conventions from this file. Thanks for posting! It will require a bit of tweaking and scaling but it's the first female version .pdo I've found. Kudos!!
Actually you can DL the template and build it yourself with minimal cost. The template is done by XenonRay, and he has a knack for making (relatively) easy to build templates. so give it a try if you would like.
