It's actually a little difficult, considering the kind of paper I used this time, because it was plain art pad paper, which the kinds I get usually are very thick lolz but usually, I just draw on very thin pieces of scanner paper, then lay a new piece of paper over the old frame, and change the image slightly. ^^
Sheesh, this is actually good. A lot of 4-legged run cycles that I've seen on deviantart are pretty lame... but not this one. The only thing I would say you didn't take into consideration (or simply biffed a little bit) is the loop on the head, and perhaps the hind legs. Anyway, awesome.
Thank you so much I tend to have trouble with forward run cycles, so I'm still practicing with how they move. I'm hoping to color these frames later, so I'm gonna try to fix the head and hind legs' movement. ^^
