Well,you certainly have some musculature to you.Glad you are not another one of the liars speaking about their ';athletic' build.And agreed about your shoulders pitching forward even from first pics. Still would like to see narrower shoulder jacket on you. Just a more perpendicular drop of the armhole would help as I said before. I just think you are creating too much of a top heavy look. Note, I have somewhat similar issues. Here is a crude pic with juvenile painting(only have a mouse,ugh).
As for your shirt, I actually think it is too fitted. A bit grabby right below your pecs and around to the sides.
Thanks gambit. Today's my tailor is coming to make some extra adjustments to this jacket, I would liked to see a tailor response on weather it could be shortened 1" or not, so I'll have to talk that with him. Also I will talk this that you commented me. Thanks again!
