Out of curiosity, how are you animating this?
I'm using Photoshop for the most part. So each frame is just one layer, rather than a body and four separate legs for a total of 5 layers. Originally I intended to build it up that way, and animate the legs in Anime Studio, but from the limited experience I have with animating trees I learned that raster images don't bend well with bone animation. Since I want this one looking the best it can, I decided to paint each main frame separately, and then tweak them in Anime Studio so they blend well.
4th pass is done, and my head is hurting now from working on this and nothing else <img src="smileys/smiley17.gif" border="0" align="middle" />

The legs should now look a lot smoother as they hit the ground, but the front left leg seems to kick or spasm when it's in the air, so I'll have to fix that. Smoothed out the head so he doesn't seem to be rocking out <img src="smileys/smiley17.gif" border="0" align="middle" />, and edited the tail a teeny bit. Also brought the rear end down a touch, but it may still need to be lower.
Going to take a break from this run animation for a day or two, since it was driving me crazy today. I'm not sure if I've made it worse with this update! So as usual I'd love to hear your critique, but I'll let it all settle in for a day or two before putting your awesome feedback into effect.
Many thanks <img src="smileys/smiley1.gif" border="0" align="middle" />
