First and foremost, I used the following animation as a reference:

The movement of it was perfect to me as I like light movements rather that exaggerated movement/bouncing.

So this took far too long... But it was worth it. So the changes made from head to toe.
Head actually bobs with every step.
Shoulders shift in a better way.
Arms actually move.
Breasts bounce better.
Hip movement is a little better.
Leg movement is nice and smooth.

So Ophira herself is 9 unique frames with those 9 frames mirrored for the left or right leg movement.
The background is 32 unique frames... I had nearly finished it last night, however the background had too many colors and making it into a gif ruined it, so I had to redo the white gradiant in the background from 10 iterations down to 5.

Anyway, enjoy.
