I'm sorry, this lemming is actually rehearsing for a ballet performance and doesn't succumb to the peer pressure of moving like your run-of-the-mill lemming /s

In all seriousness, I get what you mean but animals all have several gaits, some of which have both limbs on one side moving in unison (e.g. when dogs amble or pace)

As for the negative space, I had a hard time with it but I'll try to refine it as someone else also said the back leg looks like a poop!

Thanks for the feedback!
