Unzipping Simca's boot - 1

First of four pinups depicting, well, Simca [シムカ] from Air Gear unzipping and removing one of her boots :-P
A preview sketch to be cleaned up and maybe coloured once I get them all penciled down.

Second sketch is here [link]
UPDATE: third sketch is here: [link]

The Magical Steps of DeBooting* are actually 7 up to 10, but only my truly loved booted ones deserve them all.
Though I dig Simca's thighhighs _very_ much.

[*Yep, I made them up myself. I'm sick.]
