CGI Tauntauns and vehicles

Why: The tauntauns as well as the snowspeeders and the walkers should be redone with CGI because they look very outdated compared to the prequels, and the quality of the graphics can be distracting to the viewer at times. If it’s too costly to do all that, at least do the tauntauns because they’re the ones that need CGI urgently. What could be done about the walkers, if ILM doesn’t want to do anything expensive, is just smooth out their movements with CGI so that they move more naturally and not look so choppy.
