Looks pretty good! The pointy deltoids look a little strange. The figure seems to have a lot of surface sinks (the infraspinatus area in pic 2 for example) which look odd.
Is there a way to bake decals with alpha down and a texture down to a new set of UV? Example: I have a texture on a plane to replicate a wall and an a number of graffiti textures with alphas on planes and I want to bake down to 1 texture, to a new plane that has a different set of UVs Thanks
