Okay, first off, this was harder than I thought. Second, I wasn't prepared for this. Third, I had to really think about this as I looked at the pictures. Fourth, I wouldn't call these my "all time" choices, but they should, represent that artist well enough. Fifth, these pictures are in order from 1-5. Sixth, there are only five. Maybe later I'll expand it to 10 if I can think of anybody that comes to mind.
1.) Tickling Mice (by Scamwich)
Of all his tickle pictures (there are not many), this one is probably my favorite because its so darn cute and playful. He really knows how to make a situation work. Nice skin tones, well drawn lineart, warm, inviting colors. Overall, cute mouse girls, foot tickling, and wonderful colors win my favor with this one.
2.) Sailor Moon (by Osaka)
The quality of his lineart is precise and crisp. It could easily be mistaken for a professional's work. He clearly has a grasp of some of the major concepts and nuances of japanese animation. Usagi is clearly struggling to overcome the sensations, but it's just not possible at this point with all those tentacles having their way...
Overall, great pose, great use of the genre, great lineart.
3.) Buffy the Vampire Slayer (by Mandell)
Though this is a sketch, it is very well done, and it's clear the artist looked at photos of Gellar in order to acurately recreate her laughing.
The zombies, ghouls, vampires, or whatever they are finally have her where they want her....and yet they do this. I detect a hint of sensuality involved here. Rather than "tickle torturing" her, they seem to be gently toying with her. Her eyecontact with the monster is important in conveying this. It could be speculated that she's enjoying this, but she's probably just thinking of a way out.
Overall, excellent likeness of Sarah Michelle Gellar. Extra points for it being foot tickling.
4.) Punishing the Town Harlot (by BAC)
BAC is arguably the best tickling artist that has ever graced the community. He is a master at what he does, and the quality of his work is evident every time. I could have chosen any number of BAC pictures to call a "fave", but this one seemed more desirable for this purpose than the others.
Alot is going on in this picture. The ***** is being screamed at, having things thrown at her, and being tickled in two places at once with another villager waiting his turn. We can see without a doubt what his intentions are.
I particularly like the old woman in this picture. She seems to have a smirk on her face, which, I can only image is due to her loathing of the woman, or the services the ***** may have given her husband.
You would think she'd sooner kill her, but because this was the punishment at the time for harlots, the old woman settles for this but looks prepared to make it count. Alternatively, maybe she's never tickled a ***** before and wants to try it out.
Overall, excellent lineart, excellent situation, excellent tickling.
5.) Furry tickled by Dinosaur (by Zero)
I'm not particularly a furry-fan, but I like this picture even as basic as it is. The dinosaur seems either in love with her or her feet, or is merely being friendly to her. For reasons not explained to us visually or otherwise, the fox lady is tied up and her top has been removed and her nipples seem errect. Which could mean this is a punishment, which has actually become a delight.
In any case, much like Scamwich's picture, I got one of those cutesy type feelings from this picture that allowed me to enjoy it. Zero is definitely capable of more, but this simple sketch wins him a spot to round out my top 5 tickling pictures.
