Well, style development is kinda like building a cake. The inspirations you enjoy being all the sweet stuff like sugar, icing, yadda yadda~
I’ve noticed that the flair of my style has always been a mixture of conscious decisions and unconscious habits, both of which usually stem from things I’ve seen. Almost everyone works like this whether they realize it or not. Thats how you get hundreds of artists who all draw the same blushy noses.
Theres nothing wrong with that, but you need to be aware of it. For example, I used to read a lot of Ctrl-Alt-Del because I HONESTLY thought it was funny. In my art back then a lot of my characters turned out really flat and boring. I wasn’t even trying to copy his style, but when my mind reached for symbols and shapes when I went to draw a hand or a mouth, thats where it went.
Which brings me to my next point, symbols and shapes. When you draw something from your head you’re not actually drawing that thing. You’re drawing your own mental representation of that thing. You’re basically reaching into your spice rack and seeing what you have every time you draw anything.
Thats why ya gotta keep it stocked. You have to do research, use references, practice practice and so forth. That way you’ll have a lot more to grab from.
A lot of my style (shamelessly) comes from the anime I watch and the comics I read. I’ve also had some more traditional training when I went to college. I like a lot of action-y stuff so I try to figure out how to make things more dynamic like improving my sense of perspective and treating the picture like the lens of a camera.
