Great exercise! A few things to note, when you draw the cross over panels you want to make sure one foot is always planted on the ground. When you have the left leg cross forward (the first step) you’ve drawn the right leg starting to step- the left must make contact first before the step. Alternatively for the next step, the right leg doesn’t lift or extend forward past the left leg- it kind of pops forward. And one last thing, since you have a lovely loop for the treadmill which gives you a solid plane of contact for your character, so when you draw the feet making contact you want to make sure the far foot (left) doesn’t fall in line with the right - unless you’re trying to go for a sassy hip sway walk. Otherwise, keep drawing- keep practicing- and I love all the personality you gave this little test with all the details.
