That's a funny smile by Kohei Yamashita who is mountain mountain. He wears green which is his color.
His work looks like this. In the world of character design, a lot of folks jump in make something and hop out and move on. Kohei sticks to his style and expands on his characters to realize an entire vision. I like the long term over the short term. But neither are necessarily better than the other.
This was the mochi dessert. It was really good. You actually pour a black sugar syrup on top and it turns out amazing.
