Trailer looked good.

one thing, the scene with Han riding the tantaun with the new background looks cartoonish. He is covering too much ground it seems like.

He has a lot of ground to cover in a very short time (it takes the snowspeeders a while to find them in the morning) so presumably Tauntauns are swift beasties otherwise Luke would be dead and Boba Fett would be Lando's coffee table ;-)

If the shot looks fake at all it's not the new background but the original model that's the problem and there is only so much you can do with a stop motion element (it does look a lot smoother now).
