If you're happy with this level of animation, then that's the level you should aim for...but don't underestimate how much work even that is.
Maurice...you are dead on correct about that....I am going on YEARS that I have been working on the lip sync for the Farragut stuff...now I see why, many times, Filmation simply showed something else when folks were talking.
However, this does go to a good point...it is a LOT of work if you want it to be...depending on the style. Don't be afraid of hard work, however. There is an old saying...if you want what everyone else has, do what they are doing...if you want MORE than the others, you have to do more.
