Ah, thank you so much! Sorry for taking so long to respond! Here’s my take on the characters, hopefully this helps!
1. So when I draw them (or anything in general), I start with a line of action to help figure out how to pose them. Then I start roughing out the shape of the heads. The line between their face helps me to pin point where to draw the eyes, nose, mouth, etc! I use a normal brush the opacity set to about 30%.
2. When you draw, everything starts with shapes, so what I did with heads I do the same for the bodies. I rough out the shapes quickly for what I’m going for. Sans is kinda small and chubby and Papyrus is tall and thin, so the shapes you draw should reflect that! Reference is always good! 😀
3. This is where I start sculpting around the shapes and start adding their faces, hands, arms, cheek bones, the details in their clothes, etc. Think of them as smaller shapes on top of shapes, haha. I’ve also began erasing some of the construction lines.
4. I just keep refining the details and erasing the construction lines until… DONE! Since their will always be something I don’t like in my work, I use the transform/warp tool in photoshop to fix some things. Like San’s mouth was too big and I pushed Papyrus’s pose out just a little bit more.
I hope this kind of helps! <:) I know this was kinda fast but that’s usually my process. But don’t get discouraged, practice helps a lot!
