Well...
Your lip sync is good, but the way you make the character act needs a bit refining. It's good enough to animate with, but if you want to make it better....
It really doesn't look like he's pointing at the ship, unless it wraps around in front of him or the end that's off-screen is just absolutely huge. It doesn't look like he's pointing at anything, really. If he's pointing at the ship, his hand should sweep into the distance. If he's wagging his finger at the person in front of him--which would be equally as effective--he should point lower, like chest-level (unless the person he's talking to is really tall). If he's just gesturing to make his point, he should raise his finger when he says "perfect" or whatever word he wants to emphasize the most.
I don't know if you wasn't to give him such a terrible poker-face and totally transparent body language, but maybe that's in the character's... character. In case it's not, you shouldn't emphasize his every movement so much.
His ear should flip when he's lying, but you overemphasize the movement by making his ear flip too much and by making him look to to the side when he's pausing. I think it'd work better if he remains looking forward and his ear doesn't fall back so much. The pause with a bit of ear twitch is just enough to indicate that he doesn't quite believe his own words but he's pressing forward anyway.
His tail looks kind of mechanical. It only wags at the end. Not that he should wag his tail more, but his tail is a part of him and should be as expressive as his arms as he talks. He should whip it a bit behind him once or twice to show his agitation. It should at least move a bit so it's not so rigid behind him as he talks.
Personally, I don't think making him smile at the end is necessary, but that just depends on the character's disposition. It looks like he's saying, "I'm innocent in all this." If you're intending that the person he's speaking to is suddenly giving him the "really angry face," he should cringe a bit and take a step back--which may look more natural.
Even though he's the only character on the screen, you should keep in mind what the person he's speaking to is doing and how he/she is reacting.
I hope that's helpful.
And please, don't loop the animation. Add a start button from now on. I'm tired of telling authors that looping is annoying.
