Hey, thanks for the details!
I'm a sucker for that era of nostalgia, despite not even being alive back then as an early 2000's kid growing up with the DS. I think practicing this will help me nail some concept art for may game over here: https://wasabiiii.itch.io/grass-elemental-demo-demo
The gameboy Sugimori style is what I'm going for, I've already experimented with it in the aesthetic for my game. I'm not the best digital artist, but I think I can get somewhere close if I try!
