1st run cycle

First off, congratulations on your first animation. It loops really well, and it runs smoothly.

Here are a few things I'd like you to improve on.

1) The animation is smoothest and the paws are coming together, but when they start moving apart it gets jumpy, I think you need a few more frames.

2) As you noted the anatomy is a little off, I think what you did is that you drew the outline first instead of animating the skeleton sketch, which you may want to do first next time.

3) The head. It should be more down and forward and it isn't moving enough, it looks like you didn't want to have to re-draw it every time (and considering the amount of frames I don't blame you) but I suggest you look at some animals moving and mimic that, when in doubt you-tube, italian greyhounds make really good models.

All in all its not bad, just rough. Start with a sketch next time, all those circles and lines that are so annoying, but will keep the anatomy in line. Also, ignore the stars, I don't like the system they've set up.
