It was self taught, plenty of anatomy books, but! references help a lot, really, to see where muscles are and how bones move, etc
I am not sure how to reply to this anon, let’s see… hmmm I’ve been drawing since I was little, but took it seriously until I was 14-15, you know, learning anatomy mostly.
I kept a ‘consistent’ style from then until I was 21-22 when I started to work with digital tools, such as PS and it was then when I saw a huge improvement, also my style changed, I tried to work with a more realistic style.
So I wouldn’t know how long it took me, there were gaps of time where I didn’t see any improvement but to be fair I didn’t practice much, so I guess, and this is approximately, around 5 years with my current style.
