how come you stop animating ?

This animation like the others, is unstable. It looks like their bodies are moving for no reason at all, and tom opens his mouth when dan is talking. And you shouldn't ever be in a rush to animate, that's the opposite of what it is. If you ARE in a rush, stop animating and come back to it when you can. Don't just whip something up in a short period of time, and rush out, because that's just bad, and it is bad. Try harder, don't rush, EVER, and put your heart into it, this has none of that.

You really didn't put any effort in this, however work at your craft and improve.

Cool man

This cartoon shows much improvement from previous animations. Nicely done. However, the timing of the animations is a little off sync, the mouth movements in particular near the end. Also, it seems weird that in a comedy cartoon when Dan says get off me that Tom's not touching him. Nonetheless, you're getting better at this and it'll improve further with practice. Thanks for sharing.
