In my mind asking how people come up with concept art and if there are any tutorials on how people come up with and create their own concept art sounds crazy, as I think it's largely a matter of imagination, and what one can see in their minds eye. Still I find myself asking the question.
I feel like I have a pretty sturdy concept of drawing, I am pretty confident in my ability to draw---"What I see", but it's what I don't see that I struggle the most with. I want to create characters for a story, so I spend sometimes hours looking through pictures after pictures of body shapes and faces I think might match the character, but at the end of the day, I still can't really see the face and the proportions of this character at least not clearly enough to bring it to the table.
So I ask:
1.) How do people visualize and imagine character's in their head. The facial features and body, how do they see it? Conjure it into being? Do they spend their days looking for photo references of someone who resembles what they want?
2.) Are there any tutorials on visualization and concept art techniques, on character creation for drawing?
3.) Any tips anyone here would recommend for manifesting a character's visual existence onto the page?
