I've been practicing for about four years now, and following you for a bit of that Nim.I just watched a charcoal tutorial where the artist used a ref for a lowland gorilla, he didn't show it but you could see him glancing at it as he added the dark tones.Not of great note?Aaron Blaise. Former Disney character artist, story board artist, and animator with a pile of titles we've all seen under his belt.And what do you know, he still uses references...Good artists are Bqad artists that Never Stopped!
