Gosh your style is so smooth and delicate! It's a bit similar to the original game's style, but with its own personality. I like how you interpreted the clothes, Kiyo's like a little worm, cute. I want to comfort that poor child sooo badly... He has a lot to go through.
By the way, I'm the author of the pixel sprite. Here's the original post. I'm very pleased that it inspired you! :D
So I take it you liked the video of little crying Korekiyo.
Well, I drew you Korekiyo
(Pixelated Korekiyo was found here, I don't remember the author.)
But the drawing is mine.
