A few adjustments could possibly make it perfect.

Firstly, let me say that Tarzan is a wonderful piece of animation with CG-backgrounds blending in flawlessly behind 2D rendered characters. In some movies I CG-backgrounds ugly and unpleasant (Titan A.E. for instance).
I like the action scenes and the soft moments, both do good jobs at catching the audience. The songs are memorable as well, probably the finest work of Phil Collins as a singer/songwriter.
And now for my few adjustments. They should have scrapped Clayton as the villain and made Sabor the main villain. Sapora kills Tarzan's parents! And brutally battles Tarzan in one scene! I would have loved to see more of that.
Perhaps that would have changed the story significantly, but I would still love to see it. Aside from that little thing I really like the final product
