I want to know can Blender achieve these two technique if so how? I am using Photoshop as my external painting software or can Blender do this Internally? Note I want a painterly effect not a texture looking effect like in video games but like they do at disney… thanks 
Welp 6 years later yes, I don’t think its as in depth yet but its possible with the new 2D tools to use a 3D mesh as a proxy to paint 2D images. They behave as their own layers and can even be drawn in 3D by coiling around the 3D object. The effect is really cool
In blender 2.8 make a grease pencil layer. Then in draw mode set the stroke placement from origin to surface.
