BioWare has posted detailed PDFs showing off the bods of Cora and Liam. In standard uniforms, anyway. Their goals in providing these are to encourage this diverse community of creators and to aid these creators in making awesome art, be it with all the tiny details or just the basic features. Here's the link: blog.bioware.com/2017/01/31/mass-effect-andromeda-character-kits.
Now, they are PDFs and not just high resolution images, or at least that's what my phone said when I tried to download them.
