Attached are todays pics of Antonio with the first front/back sample. I've created it without the sleeves to allow for mistakes and changes. This sample only requires few changes.

First, I need to ease up tension around the neckline...not sure how I'm going to approach that. I may need to drop the neck hole line while still keeping the original neck hole measurements. I think the tension is being created by the neck hole working its may up the neck, or possibly cause the fabric is muslin, a coarse and stiff fabric.

Second, I may lengthen the shoulder line out further so that there is more of a linear drop for the sleeve...may take it out quarter inch to a half. I'll debate that later.
Thirdly, and whats going to be interesting to see, is the end of where the back yoke meets the back block.

As you can see in the pics, this part has created an excess of fabric not needed. This is because the line between the yoke pattern and back pattern are straight.
However, Antonio's back across his mid shoulders is curved because of the natural shape of the body. This means I'll have to slice off extra fabric while blending in to the original line and developing a curved line to fall over those natural curves. This will create an even more fitted and clean look. The less fabric, the better.
I believe this line will change with every person I encounter, seeing how each persons body is different.
In the image of the line in question, you can see where it's pinned and folded over itself to demonstrate the desired appearance...a much better look than previously.

I'll make those necessary changes and include a sleeve and collar on the next fitting.
Overall, I am very satisfied with the direction this concept is taking.
