Nice cow
Squigo is starting to loose his sketchy look (I liked his first look, although most 1st animations often look gayer then their final look) and because you still have the lined paper background you need to give him that first sketchy quality that he had otherwise he looks like he's moonwalking all over the place.
The cow was okay but her udder didn't move around alot and was a bit small (sorry I like them big and tender so I know their lactating). The last bit was really funny having the cow eat the grass sideways.
