Alekssander: it's better to render in VUE. Export your model in DXF or COB format and load it in VUE.

But you can do some texturing in Metasequoia. Go to this link :

There is a little tutorial about materials in Metasequoia. You could create the mouth with "blobby" objects. For the "ears" : begin with a cylinder or a sphere and then work with the "magnetic move" tool...
