Trying to improve on my strut I managed to create a walk that I was really pleased with..it's not much of a strut, but as a normal walk I think the movement is pretty good.
I also tried out a creeping walk. I had to add in a fair few frames for this one as it moved a bit too quick for a creeping movement, however I think it works quite well now. To improve it though I could make it more exaggerated - have the character leaning/ arching a little further back and maybe forwards a bit more. The front arms on the forwards motion could also move a little more as they appear to remain in one position for quite a while when they would naturally be moving forward with the body.
