A few people were asking for references for the TSWFBY kids- so I figured I'd start with the hardest one to draw! I'm always trying to improve, so this is more of a general guide rather than a strict set of rules to follow. : )
Things to keep track of with Orange:
-His hair is the most finicky part about him- generally it goes up into almost a point. His sideburns reach down to his shoulders. You might think of it as a sort of combination of Kirishima and Bakugo from My Hero Academia.
-He has the pointiest nose, and the bushiest eyebrows of all the kids.
-His chin is pointy, and not a circle like some of the other kids.
-He has a small bit of muscle on his arms.
-There is an 'X' pattern on the outer-side of his shoes.
-If it weren't for his hair, he and Cyan would be the same hight.
Digital drawing in general:
-For lighting, I usually have two multiply layers, an overlay layer, and a dodge layer all around half opacity. The colors shown above are one that I commonly use, but I switch them up depending on the setting and mood. I set all these to clip over the folder that holds the character line art and colors.
-I also put the faces on different layers so I can get them juuuust right without erasing the rest of the line art.
