I've never been into FNAF fan art, even fetish oriented one. But you managed to catch my attention with those feet and toes, congratulations! :)

Me either, usually. So I tried to draw this in a way that would appeal to me, as a disinterested third party.
Glad that it worked for you!! ^^ Thanks!

I can see why you had a preference for this type of lighting. It certainly reminds me of the stage they play on within the games themselves of the originals, and so acts more like a spotlight to the center stage, even if nobody is there atm and all one can do is hear rather helpless laughter. Because Kaa is making good use of his hypnosis, the most Freddy can do now is wobble in place, likely barely putting out much resistance against the snake. (if anything Kass was using the ole swirly eyes to keep him still enough to coil around him in the first place.) Gotta say, really dig how you added scratchiness to the tile flooring with the scratches to help give that abandoned feeling of the complex as well as adding wood marks to the stage itself. The soft almost twilight glow to this picture brings out the colors a pinch more than the blue lighting. Kaa looks so gleefully evil faced as he leers at the helpless hypnotized 'scary' bear. And all Freddy Fazbear can do is look back at him, umable to fully close both eyes and forced to look into them. Uselessly feeling his cute chubby toes flail about as he huhuhuhus~Just a lone digging of the snake's tail is sending him into a bubbly frenzy as it sinks into his soft doughy feet. Trailing about and slowly dragging about his supple sole as he struggles to move his face away from the sight of those swirly eyes. Pretty sure most his palms can do and touch and slide against the wood stage in panic as his foot gets some well deserved tormenting treatment. His feet are so girthy and cute, and those chubby toes are flailing about so helplessly. Quite a fan of the helpless begging as he pleads for mercy between his laughing fit. Ya know, looking at this, I just can't unsee that in a bit Kaa will hiss...slithering that tongue right around the hollow of his ear as an extra sense of ticklish waves shock thru Freddy's body. Five Night's At Freddys? More like Five Nights of Giggles With Kaa. I can see him heading back into the vents and doing this each day for the week just to torment him further each night. I mean, Kaa can slither thru vents, he can stalk the bear easily enough!

I don't know if I prefer it, but warmer colors usually draw me in first. The more overt nighttime filter works great too, since it ads to the sense of isolation...that Freddy is stuck in the restaurant all alone with the big serpent.
You have a good eye for detail, thanks for noticing all those finishing texture touches!
Rolexroche specifically requested more rotund, spherical, more plush feet. So that took some refinement to get right. :P
