It's super hard to believe it now, but I aped Ayami Kojima a ton early on (particularly castlevania art, since this was before my family even had a computer or internets and googles)
Then another artist I aped a lot (which doesn't show anymore either) is Oki Mamiya, though this was later... In hum, 2005 or so.
Then a bit after that I took quite a bit of Miyamoto Kano's style
Then of course there's Phobs on deviantart, who I used to actually try to consciously ape ever since I joined DA (a decade ago) and grow frustrated because I SUCK
Now it looks like this so...Nothing learned 0/10
