Huh.. the colors are a bit different. You can take my name off of that, if you want... The eyes used on that face exist in the game, the hair is modified from a female singer's, the hat is a modified Forest Minish's, and the body is just Link's, recolored. Actually, that body and hat have been altered since you put them in your avatar. I may or may not use Link's running animation when I animate my Kokiri sprites... probably not, in order to keep the number of sprites smaller.
Regarding the Deku Tree, I could probably turn that into a boss... but that doesn't help in making a real Great Deku Tree...
