His arms stop from traveling backwards, should probably give it some more movement.

Yay for epic-slow-motion running?

I think speeding this up more would help loads, but ff might be screwing up the playing speed.

It's better, but I'm not feeling his weight yet.
Did you even look at anything we've given you?

Anyway

Make sure he doesn't go down and bend his leg immidiately, that's the down; there's a contact frame before that.
So:
Contact (both feet are touching the ground) Down (Arms at their widest point, one foot on the ground and that same leg is bent, compensating for the newly acquired weight, also the lowest part in the animation) Passing Position (i.e. arms and legs are passing each other)  Up (Highest point) Contact (With opposite leg)

That's the formula for a walk.  I think you should start with walks, easier to do, it's more in control.
Richard Williams put runs nicely;  it went something like "Runs are even more out of control than walks, in a walk we are continually falling and catching ourselves.  The faster we go the more out of balance we are."  This isn't really a quote, I'm mashing up the idea of several chapters into there but you get the idea.

So, my advice:
Work on walks instead, do lots and lots of research

But, that's kind of a shitty thing to say as you've put a lot of work into this already.  So, my critique for what you have here would be:
Make it faster, less perfectly controlled, more crazy, and have the feet in the air even more visibly.
Really, really look at the links you've been given, especially:
http://www.wayofthepixel.net/pixelation/index.php?topic=7876.0

TONS of good information there.
This isn't a place to dump work.  It's a place to listen for critique, apply it as best as you can and screw things up majorly so you'll learn.  Make mistakes.  Go out of your comfort zone.  Listen to critique.  Screw up, learn and end up like us.  I still suck, and I'm still absorbing all of the things I've learned.

Anyone, let me know if what I've said is either assy or incorrect.  I've have to look up runs in The Animators Survival Kit for you, I know more about walks currently but I'll find some stuff for you.

I have been tempted to do a similar reply to the one Shrike did two or three times during the reading of this thread, but I still can think we can end with something good from here... 

Plat, really... I want to enter in your head to visualise the problem, so, try to answer... Why don' t you fix the problems with the axis?

a) You don't  understand what we say about the axis?
b) You do understand, but you don't care?

If answer is "A", then, simply, ask.

What we mean when me mention the "axis" is this: (Again, it' s not perfect, it has a problem in frame 8, but is "good as an example")


Look at Indy' s head. It moves... up, and down. It doesn't move left or right. Your does. Also, notice that the "shape" of the head does not change... Nobody' s head shape changes (Except Kennedy). "Your heads" does.

Look at Indy' s torso... It moves. Sometimes you can see his chest, somethimes the back... Sometimes we see the shirt, sometimes the back side of the jackett... That' s because it's rotating over a vertical axis. It' s like if we lean a bit Indy' s body after nailing him with a long stick that enters from the top of his head and gets out through his annus (eeeek).

But it does not move right or left.

Your sprite does all those things... That gives a "shacking" feeling that is not cool...

Now, if answer is "b", if you understand what we say, but you don't care, then I am off...
