I sculpted a kind of awful model and wanted to make a little scene out of it. After retopologizing and rigging, frames from my animation look like this:
The JPEG compression is pretty bad (sorry, my original file was way too big) but the shadows follow the topology of the mesh to the point that they outline the polygons and individual ones are visible.
Why are the shadows following the mesh while the texture is mostly indifferent? I've added a subsurf modifier, but the problem only shrinks a bit and the lag grows a ton. Thanks for any help you can provide!

Sorry, my other image demonstrating the problem was not great... Here's another one (scaled 200% with no interpolation).
