Normally, I'd file "character driving backwards" under lazy and not approve it... but at least some actual sprite editing went into this, and I had a giggle, so I'll let it pass.
(but if anyone else tries to do the exact same thing, they ain't getting in)
Jokes aside, adding the shades actually helped my spriting a bit (I'm making a fangame) so thanks for making the sprites! They're old, but I still really like them!
