I dunno... You learn different twitch movements when dealing with "live medium", like paint, to control the brush stroke in ways that a digital medium does not capture. For instance, using a liner with payne's grey around an eyeball, you can twitch the bristles to go just a little one way or another with very subtle movements that you cant get with a digital stylus pad. To get the same effect, you often have to create multiple layers on top, and do teensy tiny brush actions zoomed way in.
Being the child of a former professional artist, you just cant escape without picking up lots of different techniques in multiple mediums. I got essentially what counts as a formal art training over an entire childhood...
(My mother used to be a professional artist for Chance Rides inc, back in the 1990s, when they were the "World's finest", before they were downsized into oblivion by an injected banking financial partner. She did a lot of hand painting work on the "Show" animals that go on the outer ring of a carousel, and also designed and carved many of their unique animal designs. Before hiring her, they mostly used retouched Bradley and Kaye animals, but afterwards they got many unique ones, like a
triceratops. (That was created during the last year mom worked there, and has a story behind it. The bank's financial "advisor" had ordered the destruction of the original mold plug for the rhinoceros, which is a crime against art--- (The original mold plug is used to recreate the mold, and is the *ORIGINAL* art.) Rather than see it totally destroyed, and leave nothing behind but a void, mom and several co-conspirators salvaged the sawed up parts from the refuse bin, and created the triceratops from it, using automotive bondo, marine grade fiberglass resin, a pair of nylon pantyhose, some modeling clay, and 2 wooden dowels. They did it in secret, and presented it to the owner, Dick Chance, the next time he made a tour, as a personal present.) It's fun for me to see Chance carousels, because I REMEMBER mom making the original art for many of their panels, and riders as well. For instance, the "Jester head" panels that go on the 50ft "Grand" carousel,
as seen in this brochure were made using high density foamboard, and yellow children's modeling clay on our kitchen table. The model for the golden liberty seen there on the rider bench, is actually my aunt Joyanne, My mom's sister. LOL. Her work is literally all over the world, and even in the smithsonian, but she herself is a figure of obscurity. I cant even begin to describe how "Crazy-good" she is.)
