Awww! Beautiful collection. I didn't know there are so many different Lisa sprites around.
Some of them are familiar (say, the one with the rope, it's from the Arcade Game if I'm not mistaken... the second to the most cute one here, guess which one's the winner ), but others are new. Very unusual and nicely done piece of art, I like it.

And... the grownup Lisa inside of the building, in dark coat and glasses, she reminds me of the Child of Darkness.

Dark Mage
Ooh, so you actually drew most of them? Kudos then, it surely was lots of work.
I checked the picture more carefully, here's the list of all canons I could recognize (from left to right):

- Lisa in blue/red stripy outfit - "Cool Lisa" from the "Summer Of 4 Ft. 2" episode (where's her hat btw? ).
- With the skipping rope - from the Simpsons Arcade game.
- Hiding in the building - Lisa from Graham's CoD.
- Holding the mailbox in her hand - Mighty Lisa from one of the Halloweens.
- Long-haired weird-haircut parrot-suit - from the new game.
- Winged Lisa on the tree - aww, maybe from my story? There was a line when she spent a night on the tree ^^
- Anime-dressed - Steve's Simpson Moon Lisa of course! (love her expression )
- With dark glasses, in the middle of the jump - not sure, but her hairstyle reminds me of Graham's Lisa^2 for some reason.
- High above in the sky, green eyes - Evil Lisa from one of the official comics. She got mocked badly there and turned into some dark being, punishing all the mockers.

Others I've missed. Maybe someone will recognize more.

The ones that come to mind are:

- Lisa from the Arcade game (Both the jump rope & green superhero outfit in top right corner (not glowing green though ))
- Cool Lisa from 3F22
- Clobber Girl (Mailbox)
- Lisa the Conjurer (Orange Cape)
- The Jazzler (Sax)
- Big Super Happy Fun Fun Lisa (Linguo)

Impressive collection of Sprites though.

Let's mark off the Lisas, shall we?  From left to right:

You're half-right with the two in the bottom left, Marco.  The dark-haired girl is Lisa's alternate disguise in my RPG, however the one she's fighting is Lisa from Steve's RPG.

Yep, that's Lisa the Conjurer menacing Cool Lisa (as for her hat... um, well, I suck at hats.  Really.  I'm surprised The Jazzler's beret turned out as well as it did), but that's not a swimsuit-wearing Lisa she's pushing aside, she's protecting Lisa Fitzgerald, who's wearing some overalls and clutching a Binky doll.  I suppose it's a bit hard to tell.

And yeah, that's the Arcade Lisa, though I wasn't really going for menacing, more like, 'everybody else gets superpowers but all I get is a jump rope?'

CoD Lisa in the darkness, and The Jazzler fighting Clobber Girl just outside.  A winged Lisa up in the tree (sorry Serge, with so many Winged Lisas around, I just went for a generic one instead.  No particular fanfic or fanart) and, correct Marco, Suzy down below, looking upwards at her.

Serge and ALM are right, that's Anime Lisa with Linguo from the new Simpsons game, facing off with Sailor Moon-Lisa.

You are right Marco, that is indeed Sam, from Steve's Explorers fic.

Ah, now, the Link Lisa.  Good pick Marco, (though, I suppose it's not hard to guess) that's from an idea I had once and attempted to write.  Haven't given up on it though.

Serge, I'm surprised you didn't get Lisa's superhero costume from the Arcade game.   And the green-glowy one, sorry, but as Marco guessed, that's Sprite from The Justice League of Springfield by Steve (not Chris ).  I actually thought about including the evil, kill kill Lisa from the comics, but I figured two glowy Lisas with superpowers were enough. (and besides, Sprite was there first. )

Dark Mage

Argle, I suspected that, but wasn't sure what she holds in her hand, does look like Binky actually (but I must say that there was no Binky in the first, more known version of LF), even if it's just several pixels size. Her expression also kinda tells who's she... and I like that's she being protected there.

*enjoy this picture* ^^
