The voice acting needs alot more work than the artwork--though, the artwork could use work.
I can still barely understand Whitestorm. The volume of his voice seems half the volume of anyone else. And the voice actors need to put emotion into their lines. The more monotone they speak, the harder it is to understand. Subtitles would help.
The artwork in the closing credits was much better than the artwork in the animation. During the clan meeting, one of the cats in the crowd looked like a doberman. Lionheart is starting to look ridiculous to me (he reminds me of a pokemon) --but maybe that's just me.
(At one point, I was expecting Lionheart to pick Kit up by the scruff of the neck and present him to the clan while they all roared (or yowled) and "Circle of Life" was playing in the background, but that's another story. But seriously, it would be so easy to make a parody of this.)
Playing music during the dialogue is distracting, even if you keep it down. Even without music to distract me, I have trouble understanding them sometimes. In general, music should be played when there's very little or no dialogue.
I still find the series interesting enough to keep up with. But I'm still deducting a point because I think the author needs to post his own work himself.
